Dynamic Grid Trading Strategy v1.0
Cron-driven grid bot for EVM L2 chains via onchainos CLI. Features asymmetric grid steps — different spacing for buy vs sell sides based on trend direction, trend intelligence with multi-timeframe analysis, sell optimization, and HODL Alpha tracking.
Every tick: fetch price → MTF analysis → compute grid level → trend-adaptive decision → execute swap → report to Discord.
Asymmetric Grid Steps
Buy and sell sides use different spacing based on trend direction:
| Trend | Buy Side | Sell Side | Effect |
|---|
| Bullish | Tighter (accumulate fast) | Wider (hold longer) | Buy dense, sell sparse → captures uptrend |
| Bearish | Wider (wait for dip) | Tighter (exit fast) | Sell dense, buy sparse → reduces downside exposure |
| Neutral/Weak | Symmetric | Symmetric | Symmetric (default) |
Key config: ASYM_FACTOR=0.4 (max asymmetry ratio). Asymmetry scales with trend strength and only activates when strength > 0.3.
New grid dict fields: buy_step, sell_step (backward-compatible step = average). Level prices are now non-uniform: below center spaced by buy_step, above center by sell_step.

OKX Skill Dependencies (command syntax defined in each skill, do not duplicate here):
okx-dex-swap — quote, approve, swap execution
okx-dex-market — K-line / OHLC data
okx-agentic-wallet — wallet switch, balance, contract-call (TEE signing)
okx-onchain-gateway — transaction simulation
Pipeline: Execution Steps
CRITICAL RULE: Steps MUST execute in order. Do NOT skip steps or proceed past a gate that has not been satisfied.
Step 1: Data Acquisition
Actions:
- Fetch ETH price via
okx-dex-swap (swap quote)
- Fetch on-chain balances via
okx-agentic-wallet (wallet balance)
- Update
price_history (append, cap at 288 = 24h @ 5min)
- Detect external deposits/withdrawals (unexplained balance changes > $100)
Gate (ALL must pass):
Step 2: Multi-Timeframe Analysis
Actions:
- Compute short EMA (25min / 5-bar), medium EMA (1h / 12-bar), long EMA (4h / 48-bar)
- Detect EMA alignment → trend direction (bullish / bearish / neutral) + strength (0-1)
- Detect 8h structure: split into 4 segments, check higher-highs/higher-lows → uptrend / downtrend / ranging
- Compute 1h and 4h momentum
- Fetch K-line data (1H candles, 24 bars) → compute ATR-based volatility (hourly cache)
Output: mtf dict, kline_vol float
def analyze_multi_timeframe(history, price) -> dict:
# Returns {trend, strength, momentum_1h, momentum_4h, structure,
# ema_short, ema_medium, ema_long}
# EMA alignment: short > medium > long → bullish
# Structure: 8h window split into 4 segments
# higher-highs + higher-lows → "uptrend"
# lower-highs + lower-lows → "downtrend"
# else → "ranging"
Gate:
Step 3: Grid Decision
Actions:
- Calculate dynamic grid with trend-adaptive volatility multiplier:
- Grid center = EMA(20) on 1H kline (20-hour EMA, fetched via
okx-dex-market kline). Falls back to 5min tick history if kline unavailable.
- Base:
VOLATILITY_MULTIPLIER_BASE=2.0
- In trend (strength > 0.3): blend toward
VOLATILITY_MULTIPLIER_TREND=3.0
- Wider grid in trends → fewer trades → more holding
- Check recalibration triggers (breakout / vol shift / age)
- Map price → grid level
- If level changed: determine direction (BUY if level dropped, SELL if rose)
- Safety checks: cooldown, trend-adaptive position limits, repeat guard, consecutive limit
- Sell optimization: if SELL in strong uptrend, delay via
_should_delay_sell()
- Calculate trade size with trend-adaptive sizing
Gate:
Step 4: Execution
Actions:
- Get swap quote + tx data from OKX DEX aggregator
- Pre-simulate via
okx-onchain-gateway (diagnostic, non-blocking)
- For BUY: ensure USDC approval via
okx-dex-swap
- Sign + broadcast via
okx-agentic-wallet contract-call (TEE signing)
- On failure: 1 auto-retry with 3s delay and fresh quote
- Record trade in state, update grid level ONLY on success
Gate:
Step 5: Notification & Tracking
Actions:
- Calculate PnL (USD + ETH denominated)
- Calculate HODL Alpha:
current_portfolio - (initial_eth × current_price)
- Build structured JSON output for AI agent parsing
- Send Discord embed (green=SELL, blue=BUY, grey=no-trade, red=stop)
- Emit
---JSON--- block with enriched fields
Output: Discord notification + structured JSON
Tunable Parameters
Grid Structure
| Parameter | Default | Description |
|---|
GRID_LEVELS | 6 | Number of grid levels. More = finer, more trades |
GRID_TYPE | "arithmetic" | "arithmetic" (fixed $ step) or "geometric" (fixed % step) |
EMA_PERIOD | 20 | EMA lookback for grid center (applied to 1H kline = 20h) |
VOLATILITY_MULTIPLIER_BASE | 2.0 | Base grid width = multiplier x stddev |
VOLATILITY_MULTIPLIER_TREND | 3.0 | Wider grid in trending markets |
ASYM_FACTOR | 0.4 | Max buy/sell asymmetry ratio. 0=symmetric, 1=fully asymmetric |
GRID_RECALIBRATE_HOURS | 12 | Max hours before forced recalibration |
Multi-Timeframe
| Parameter | Default | Description |
|---|
MTF_SHORT_PERIOD | 5 | 5-bar EMA (25min @ 5min tick) |
MTF_MEDIUM_PERIOD | 12 | 12-bar EMA (1h @ 5min tick) |
MTF_LONG_PERIOD | 48 | 48-bar EMA (4h @ 5min tick) |
MTF_STRUCTURE_PERIOD | 96 | 96-bar (8h @ 5min tick) for structure detection |
Sell Optimization
| Parameter | Default | Description |
|---|
SELL_TRAIL_TICKS | 2 | Wait 2 ticks (10min) of price stability before selling in uptrend |
SELL_MOMENTUM_THRESHOLD | 0.005 | Skip sell if 1h momentum > 0.5% in strong uptrend |
Grid Modes
Arithmetic (等差网格): Each level is a fixed USD distance apart. Good for narrow ranges.
levels = [center - N*step, ..., center, ..., center + N*step]
Geometric (等比网格): Each level is a fixed percentage apart. Better for wide ranges because step size scales with price. The ratio is derived from the arithmetic step: ratio = 1 + (step / center).
# In calc_dynamic_grid(), when GRID_TYPE == "geometric":
ratio = 1 + (step / center)
level_prices = [center * (ratio ** (i - half)) for i in range(GRID_LEVELS + 1)]
Both modes store level_prices in the grid dict for unified level lookup via bisect_right. Asymmetric spacing uses levels below center spaced by buy_step, levels above by sell_step. The _build_level_prices() helper handles both symmetric and asymmetric construction.
Choosing a mode:
| Market | Recommended | Why |
|---|
| Tight range ($1900-$2100) | Arithmetic | Even spacing, predictable profit per grid |
| Wide range ($1500-$3000) | Geometric | Steps scale with price, avoids crowding at low end |
| High volatility | Geometric | Naturally wider steps at higher prices |
| Stablecoin pairs | Arithmetic | Fixed small steps (0.1-0.5%) |
Adaptive Step Sizing
Step scales with real-time volatility, modulated by trend strength. Splits into directional buy/sell steps:
vol_mult = VOLATILITY_MULTIPLIER_BASE (2.0)
if trend_strength > 0.3:
vol_mult = blend(BASE, TREND, strength) (up to 3.0)
# Asymmetric steps based on trend direction
asym = ASYM_FACTOR × strength (if strength > 0.3, else 0)
if bullish:
buy_mult = vol_mult × (1 - asym) # tighter buy
sell_mult = vol_mult × (1 + asym) # wider sell
elif bearish:
buy_mult = vol_mult × (1 + asym) # wider buy
sell_mult = vol_mult × (1 - asym) # tighter sell
buy_step = (buy_mult × ATR) / (GRID_LEVELS / 2)
sell_step = (sell_mult × ATR) / (GRID_LEVELS / 2)
# Both clamped to [price × STEP_MIN_PCT, price × STEP_MAX_PCT], floor $5
step = (buy_step + sell_step) / 2 # backward-compatible average
| Parameter | Default | Description |
|---|
STEP_MIN_PCT | 0.010 | Step floor as fraction of price (1.0%) |
STEP_MAX_PCT | 0.060 | Step cap as fraction of price (6%) |
VOL_RECALIBRATE_RATIO | 0.3 | Recalibrate if kline ATR shifts >30% from grid's stored ATR |
Recalibration triggers (asymmetric):
- Downside breakout: Price < grid lower -
buy_step → recalibrate immediately (buying dips is grid's edge)
- Upside breakout: Price > grid upper +
sell_step → require N consecutive ticks confirmation before recalibrating (anti-chase)
- Grid age exceeds
GRID_RECALIBRATE_HOURS
- Current kline ATR deviates >30% from grid's stored ATR
| Parameter | Default | Description |
|---|
UPSIDE_CONFIRM_TICKS | 6 | Ticks (30min @ 5min interval) price must hold above grid before upside recalibration |
MAX_CENTER_SHIFT_PCT | 0.03 | Max 3% grid center shift per recalibration (prevents chasing spikes) |
Anti-chase mechanism:
- Upside breakout counter resets if price returns to grid range before confirmation
- Even after confirmation, center shifts are capped to
MAX_CENTER_SHIFT_PCT per recalibration
- Multiple recalibrations can gradually track a true trend, but a single spike cannot drag the grid
Position Sizing Strategies
Controls how much to trade at each grid level.
| Strategy | Description |
|---|
"equal" | Every grid level trades the same amount |
"martingale" | BUY more at lower levels, SELL more at higher levels |
"anti_martingale" | Reduces exposure as price moves further from center |
"pyramid" | Largest position at grid center, tapering toward edges |
"trend_adaptive" | (default) In bullish: buy more + sell less. In bearish: sell more + buy less |
def _calc_sizing_multiplier(level, grid_levels, direction, mtf=None):
base_mult = 1.0
if SIZING_STRATEGY == "trend_adaptive" and mtf:
trend = mtf.get("trend", "neutral")
strength = mtf.get("strength", 0)
if trend == "bullish":
if direction == "BUY":
base_mult = 1.0 + strength * (MAX - 1.0) # buy aggressively
else:
base_mult = 1.0 - strength * (1.0 - MIN) # sell conservatively
elif trend == "bearish":
# opposite
...
return clamp(base_mult, SIZING_MULTIPLIER_MIN, SIZING_MULTIPLIER_MAX)
Trade Execution
| Parameter | Default | Description |
|---|
MAX_TRADE_PCT | 0.12 | Max 12% of portfolio per trade (before sizing multiplier) |
MIN_TRADE_USD | 5.0 | Minimum trade size in USD |
SLIPPAGE_PCT | 1 | Slippage tolerance for DEX swap |
GAS_RESERVE | 0.003 | Native token reserved for gas |
Risk Controls
Basic Controls
| Parameter | Default | Description |
|---|
MIN_TRADE_INTERVAL | 1800 | 30min cooldown between same-direction trades |
MAX_SAME_DIR_TRADES | 3 | Max consecutive same-direction trades |
MAX_CONSECUTIVE_ERRORS | 5 | Circuit breaker threshold |
COOLDOWN_AFTER_ERRORS | 3600 | Cooldown after circuit breaker trips |
POSITION_MAX_PCT_DEFAULT | 70 | Block BUY when ETH > this % |
POSITION_MIN_PCT_DEFAULT | 30 | Block SELL when ETH < this % |
POSITION_MAX_PCT_BULLISH | 80 | Allow more ETH in bullish trend |
POSITION_MIN_PCT_BEARISH | 25 | Allow less ETH in bearish trend |
Additional safety guards:
- Rapid drop protection: skip BUY if price dropped >2% in last 30min (6 ticks)
- Consecutive same-direction reset: limit resets if grid was recalibrated or >1h since last trade
- Anti-repeat: skip if same direction + same level boundary as last trade
- Trend-adaptive position limits: limits shift based on trend direction and strength
Stop-Loss, Trailing Stop & Take-Profit
Three protection mechanisms. When triggered, trading halts and a red Discord alert is sent. Use resume-trading command to clear.
| Parameter | Default | Description |
|---|
STOP_LOSS_PCT | 0.15 | Stop if portfolio drops 15% below cost basis |
TRAILING_STOP_PCT | 0.10 | Stop if portfolio drops 10% from peak |
def _check_stop_conditions(state, total_usd, price):
cost_basis = initial + deposits
pnl_pct = (total_usd - cost_basis) / cost_basis
peak = max(stats["portfolio_peak_usd"], total_usd)
# Check: stop_loss, trailing_stop, take_profit
Risk Control Flow in tick()
1. If stop_triggered is set → log + Discord red alert + refuse trading + return
2. Check _check_stop_conditions → if triggered, set stop_triggered + alert + return
3. Multi-timeframe analysis → get trend context
4. Normal grid logic (cooldown, trend-adaptive position limits, etc.)
5. If SELL in strong uptrend → _should_delay_sell() check
Core Algorithm
1. Fetch token price
2. Read on-chain balances (ETH + USDC)
3. Multi-timeframe analysis → trend/strength/momentum/structure
4. Fetch K-line ATR volatility (hourly cache)
5. Check if grid needs recalibration (breakout / vol shift / age)
→ calc_dynamic_grid() uses trend-adaptive volatility multiplier
→ asymmetric buy_step/sell_step based on trend direction
6. Map price → grid level
7. If level changed:
a. Direction: BUY if level dropped, SELL if rose
b. If SELL in strong uptrend → delay check (trailing + momentum protection)
c. Safety checks (cooldown, trend-adaptive position limits, repeat guard, consecutive limit)
d. Calculate trade size (trend-adaptive sizing)
e. Execute swap via DEX aggregator
f. Record trade, update level ONLY on success
8. Calculate HODL Alpha
9. Report status (JSON + Discord)
Grid Calculation
def calc_dynamic_grid(price, price_history, mtf=None):
center = EMA(1H_kline, EMA_PERIOD) # 20-hour EMA on 1H candles
atr = calc_kline_volatility(candles)
# Trend-adaptive multiplier
vol_mult = VOLATILITY_MULTIPLIER_BASE # 2.0
if mtf and mtf["strength"] > 0.3:
vol_mult = blend(BASE=2.0, TREND=3.0, factor=strength)
# Asymmetric buy/sell multipliers
asym = ASYM_FACTOR * strength if strength > 0.3 else 0
if bullish:
buy_mult = vol_mult * (1 - asym) # tighter buy grid
sell_mult = vol_mult * (1 + asym) # wider sell grid
elif bearish:
buy_mult = vol_mult * (1 + asym) # wider buy grid
sell_mult = vol_mult * (1 - asym) # tighter sell grid
buy_step = clamp((buy_mult * atr) / half, floor, ceil)
sell_step = clamp((sell_mult * atr) / half, floor, ceil)
# Build asymmetric level_prices via _build_level_prices()
# Below center: spaced by buy_step; Above center: spaced by sell_step
level_prices = _build_level_prices(center, buy_step, sell_step, half, grid_type)
return {center, step, buy_step, sell_step, levels, range, vol_pct, type, level_prices}
Examples (at price $2000, ATR=$50):
| Trend | Strength | buy_step | sell_step | Buy Range | Sell Range | Behavior |
|---|
| Neutral | 0.1 | $33 | $33 | $1901-$2000 | $2000-$2099 | Symmetric, normal |
| Bullish | 0.6 | $33 | $54 | $1901-$2000 | $2000-$2162 | Buy dense + sell wide |
| Bearish | 0.6 | $54 | $33 | $1838-$2000 | $2000-$2099 | Buy wide + sell dense |
| Strong Bull | 0.9 | $24 | $66 | $1928-$2000 | $2000-$2198 | Max asymmetry |
Sell Optimization Logic
def _should_delay_sell(state, current_level, prev_level, mtf, history):
"""Returns skip reason or None."""
# 1. Momentum protection: skip sell if 1h momentum > 0.5% in uptrend
if momentum_1h > SELL_MOMENTUM_THRESHOLD * 100:

return None
Trend-Adaptive Position Limits
def _get_position_limits(mtf):
"""Return (max_pct, min_pct) based on trend."""
if trend == "bullish" and strength > 0.3:

Trade Size
Returns (amount_in_smallest_unit, failure_info). SELL returns wei (x1e18), BUY returns uUSDC (x1e6).
def calc_trade_amount(direction, eth_bal, usdc_bal, price,
current_level=None, grid_levels=None,
mtf=None):
available_eth = eth_bal - GAS_RESERVE_ETH
total_usd = available_eth * price + usdc_bal

# Apply trend-adaptive sizing
multiplier = _calc_sizing_multiplier(level, grid_levels, direction, mtf)
max_usd *= multiplier
if direction == "SELL":
return int(min(max_usd / price, available_eth) * 1e18), None # wei
else:
return int(min(max_usd, usdc_bal * 0.95) * 1e6), None # uUSDC
Level Update Rule (Critical)
| Outcome | Update level? | Rationale |
|---|
| Trade succeeded | Yes | Grid crossing consumed |
| Trade failed | No | Retry on next tick |
| Trade skipped (cooldown/limit) | No | Don't lose the crossing |
| Sell delayed (trailing/momentum) | No | Will retry next tick |
PnL Tracking (dual-denominated)
# USD-denominated
total_pnl_usd = current_portfolio_usd - cost_basis
hodl_value_usd = initial_eth_amount × current_price
grid_alpha_usd = current_portfolio_usd - hodl_value_usd
# ETH-denominated
current_eth_equivalent = current_portfolio_usd / current_price
initial_eth_equivalent = cost_basis / initial_price
total_pnl_eth = current_eth_equivalent - initial_eth_equivalent
HODL Alpha (key metric): grid_alpha_usd > 0 means grid outperforms pure ETH holding.

Adapting to Different Pairs
| Consideration | What to adjust |
|---|
| Token decimals | USDC=6, DAI=18, WBTC=8 — affects amount conversion |
| Typical volatility | BTC lower vol → smaller STEP_MIN/MAX_PCT; meme coins → larger |
| Liquidity depth | Low liquidity → smaller MAX_TRADE_PCT, add price impact check |
| Gas costs | L1 vs L2: adjust GAS_RESERVE and MIN_TRADE_USD |
| Stablecoin pair | TOKEN/USDC pair: STEP_MIN_PCT can be much tighter (0.2%) |
| Rate limits | Add 300-500ms delay between consecutive OKX API calls |
AI Review & Optimization
AI agent should periodically review trading performance and suggest/apply optimizations. Run weekly or when cumulative PnL stalls.
Step 1: Pull & Pair Trades
Extract recent trades and pair each BUY with its corresponding SELL to form round trips.
# Matching logic: SELL from level A→B matches BUY from level B→A
buy_stack = []
round_trips = []
for trade in trades:
if trade["direction"] == "BUY":
buy_stack.append(trade)
else: # SELL
for j in range(len(buy_stack)-1, -1, -1):
if buy_stack[j]["grid_to"] == trade["grid_from"]:
matched_buy = buy_stack.pop(j)
round_trips.append((matched_buy, trade))
break
Output per round trip:
- Spread:
(sell_price - buy_price) / buy_price x 100%
- Hold time: minutes between buy and sell
- Status: profit (spread > 0.3%), micro-profit (0 < spread < 0.3%), loss (spread < 0)
Step 2: Flag Anomalies
| Flag | Condition | Meaning |
|---|
LOSS | spread < 0 | Bought high, sold low |
MICRO | 0 < spread < 0.3% | Profit too small to cover DEX costs |
GOOD | spread >= 0.3% | Healthy grid profit |
Key metrics: win rate, loss impact, micro-trade ratio (if > 30%, step too small).
Step 3: Root Cause Analysis
LOSS trades:
| Pattern | Root Cause | Fix |
|---|
| Buy @high, sell @low after recalibration | Grid chased a spike | Increase UPSIDE_CONFIRM_TICKS, reduce MAX_CENTER_SHIFT_PCT |
| Buy @high in trend, sell @low on reversal | EMA too reactive | Increase EMA_PERIOD or GRID_RECALIBRATE_HOURS |
| Loss during flash crash | Stop-loss too loose | Tighten STOP_LOSS_PCT |
MICRO trades:
| Pattern | Root Cause | Fix |
|---|
| Many trades with < 0.2% spread | Step too small | Increase STEP_MIN_PCT |
| Rapid back-and-forth at same levels | Low vol, grid too dense | Increase MIN_TRADE_INTERVAL |
| Trades cluster in 5-10 min windows | Cooldown too short | Increase MIN_TRADE_INTERVAL |
Step 4: Parameter Tuning
STEP_MIN_PCT >= DEX_total_cost x 3
where DEX_total_cost ~ slippage + price_impact ~ 0.1-0.3% on L2
→ STEP_MIN_PCT >= 0.009 to 0.012
UPSIDE_CONFIRM_TICKS = typical_spike_duration / tick_interval
e.g., spikes last ~20min, tick=5min → confirm_ticks = 4-6
MAX_CENTER_SHIFT_PCT = step_pct x 2-3
Step 5: Backtest & Apply
Simulate new parameters against historical data, then: backup → patch → recalibrate → monitor 24h → re-run analysis.
Review Checklist (AI Agent Prompt)
1. Read grid_state.json and grid_bot.log
2. Filter trades to review window (default: last 48h)
3. Pair trades into round trips
4. Compute: win_rate, avg_spread, loss_count, micro_count, total_pnl, hodl_alpha
5. If loss_count > 0: trace each loss to recalibration events
6. If micro_ratio > 30%: recommend STEP_MIN_PCT increase
7. Check MTF data for trend alignment during losses
8. Propose specific parameter changes with backtest evidence
9. On user approval: backup → patch → recalibrate → verify
Failure & Rollback
IF Step N fails:
1. Log failure reason to grid_bot.log
2. Increment errors.consecutive
3. If errors.consecutive >= 5: trigger circuit breaker (1h cooldown)
4. Cache failed trade for retry command (10min expiry)
5. DO NOT update grid level
6. Report failure via Discord + JSON output
Anti-Patterns
| Pattern | Problem |
|---|
| Recalibrate every tick | Grid oscillates, no stable levels |
| Update level on failure/skip | Silently loses grid crossings |
| No position limits | Trending market → 100% one-sided |
| Fixed step in volatile market | Too small → over-trades; too large → never triggers |
sell - buy as PnL | Net cash flow ≠ profit |
| No cooldown | Rapid swings cause burst of trades eating slippage |
| No stop-loss | Single crash wipes out months of grid profits |
| Martingale without cap | Exponential position growth → liquidation risk |
| Arithmetic grid on wide range | $20 step meaningless at $5000 but huge at $500 |
| Symmetric recalibration | Chasing upside spikes = buying high then selling low on reversal |
| Step floor too low | Micro-profit trades only feed DEX fees, net negative after costs |
| No center shift cap | Single spike can drag grid center 5%+, creating losing positions |
| Fixed sizing in trends | Selling same size in uptrend = giving away alpha to the market |
| Selling immediately in uptrend | Sell delay exists for a reason — let trends play out |
| Symmetric grid in strong trends | Asymmetric grids accumulate faster on the favorable side |
Ignoring buy_step/sell_step in profit calc | Use actual level_prices differences, not average step |
