dca-weekly

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).

Backtest reference

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.
