GRID & DCA STRATEGY

GRID

Grid Buy/Sell between Keys

When price sits inside a gap (lo, hi), open both BUY and SELL with a small TP equal to (hi−lo)/scalpRangeRatio − 0.5. No SL. Skips if a same-direction order already lives within the same distance.

→ STEP 01 · INSIDE THE GAP

// for each adjacent pair range = hi − lo distance = range / scalpRangeRatio tp = distance − 0.5 // open both sides if no nearby fill Buy(initLot, ask, ask + tp) Sell(initLot, bid, bid − tp)

Both directions fill simultaneously. HasPositionNearby blocks duplicates within the same distance window.

DCA

DCA Higher Lots at Keys

When price is within dcaEntryDistance of a key, fire a counter-trend order sized as positionCount × initLot × power. Each key may only be DCA’d once per side. Requires minCountDca existing positions to arm.

→ STEP 02 · TOUCH THE KEY

// price approaches from above → SELL // price approaches from below → BUY power = [dcaPower, dcaPower2, dcaPower3][tier] dcaLot = cnt × initLot × power SL = dcaSl // no TP, BE handles exit

Gates: must have cnt ≥ minCountDca open, key not in dcaHistory, and no DCA already being tracked.

BREAK-EVEN

Close On Breakeven and Trail

Once a DCA leg exists and aggregate profit covers any prior SL losses (slLoss1 + slLoss2), a peak trail of cnt dollars closes all same-side positions when price pulls back from the high-water mark.

→ STEP 03 · TRAIL TO EXIT

needed = |slLoss1| + |slLoss2| // only if totalProfit ≥ needed peak = max(peak, totalProfit) trail = cnt // dollars // drop below peak − trail → close all

On close, ClearDcaState wipes history, slLoss1, slLoss2, and the peak. Cycle restarts clean.

DCA LOSS RECOVERY

TIER · 0 → 1 1

First DCA stops out

Loss saved as slLoss1 (negative)
dcaHistory kept — key still locked
Next DCA uses dcaPower2
Break-even target: |slLoss1|

TIER · 1 → 2 2

Second DCA stops out

Loss saved as slLoss2
Next DCA uses dcaPower3
Break-even target: |slLoss1| + |slLoss2|
One last shot at recovery

TIER · 2 → RESET 3

Third DCA stops out

Full reset via ClearDcaState
History, slLoss1, slLoss2 all cleared
Cycle restarts at tier 0
Loss is realized — no more recovery
