Dca Weekly

Other

Use when writing, validating, or troubleshooting a recurring scheduled buy strategy (DCA, dollar-cost averaging, weekly buys, daily buys, monthly accumulation, accumulator) on Superior Trade — especially anything that should "buy more of the same pair" on a calendar trigger rather than a price trigger.

Strategy: DCA · Scheduled Buys

When to use

A user asks to "buy X every week", "DCA into BTC", "scheduled buy", "accumulator", "monthly buy", or any variation that means open a position once, then keep adding to it on a calendar cadence. Not for "buy when price drops" — that's grid trading (see grid-trading).

What it does

  • Holds one open trade per pair (Freqtrade's hard rule).
  • The first calendar trigger opens the trade with a small initial stake.
  • Every subsequent trigger calls adjust_trade_position and adds the same notional to the open trade.
  • The position grows in fills inside a single Trade row. PnL is reported per-trade.
  • Exits only when the user sets one (typically never, for true DCA — stoploss = -0.99 and no populate_exit_trend).

The (rejected_signals: 9) warning in logs is normal: populate_entry_trend keeps emitting Monday flags even while a trade is open, but adjust_trade_position does the actual buys.

The Freqtrade primitives that make this work

These four flags are the difference between v1 (1 trade ever, the rest rejected) and v2 (a real ladder of fills). All four are required:

position_adjustment_enable = True
max_entry_position_adjustment = 26   # cap on number of weekly adds
max_dca_multiplier = 27.0            # 1 initial + 26 adds

Plus two callbacks:

  • custom_stake_amount — divides the user-configured stake by max_dca_multiplier so the initial entry leaves room for the future weekly adds.
  • adjust_trade_position — the calendar trigger. Returns (stake, tag) to add, None to do nothing.

Config requirements

{
  "exchange": { "name": "hyperliquid", "pair_whitelist": ["BTC/USDC"] },
  "stake_currency": "USDC",
  "stake_amount": 1000,
  "dry_run_wallet": 10000,
  "timeframe": "1d",
  "max_open_trades": 1,
  "stoploss": -0.99,
  "minimal_roi": { "0": 100.0 },
  "entry_pricing": { "price_side": "same" },
  "exit_pricing": { "price_side": "same" },
  "pairlists": [{ "method": "StaticPairList" }]
}

stake_amount is the post-division budget the user wants per buy times max_dca_multiplier. With stake_amount: 1000 and max_dca_multiplier: 27, each Monday buy is ~$37; total budget is ~$1000.

dry_run_wallet must be ≥ stake_amount (Freqtrade keeps a 1% reserve, so the strict gate is stake_amount ≤ dry_run_wallet × 0.99). Default dry_run_wallet is 1000; bump it up if you raise stake.

Common pitfalls

  1. No position_adjustment_enable. Without it, repeat Monday flags are silently rejected and you get one trade ever. The classic v1 mistake.
  2. No same-day guard in adjust_trade_position. Without the filled[-1].order_filled_utc.date() == current_time.date() check, the strategy double-buys on the Monday the initial entry was placed.
  3. Forgetting to scale stake_amount. Without custom_stake_amount returning proposed_stake / max_dca_multiplier, the first buy uses the full configured stake and the wallet runs out before week 5.
  4. Using populate_exit_trend to "exit half". Doesn't work — Freqtrade only knows full exits via populate_exit_trend. Partial exits go through adjust_trade_position returning a negative stake.
  5. Setting stoploss ≥ -0.5. A real DCA isn't supposed to stop out on a 50% drawdown. Use -0.99 so the stop never triggers, then exit manually if needed.

Variants

  • Daily / monthly cadence: change current_time.weekday() != 0 to current_time.day != 1 (1st of month) or remove the guard entirely (every candle close).
  • Drawdown-aware DCA: add a check on current_profit < -0.10 to add EXTRA on top of the calendar — buy more when down 10%. Combine the calendar check with current_profit < threshold.
  • Spot vs futures: works on both. Use BTC/USDC for spot (trading_mode: "spot" or omit) or BTC/USDC:USDC for perp (trading_mode: "futures", margin_mode: "cross"). DCA is most idiomatic on spot.
