DCA-Down (Avg Down)

"Averaging down": you already hold a position at a loss; buying more at a lower price reduces your average cost. Plan additional buys or reverse-solve the buy needed to hit a target average.

Breakeven Move from Mkt

Formula
Forward: newAvg = (oldCost + Σ buy_i × qty_i) ÷ (oldQty + Σ qty_i)
Reverse: needQty = oldQty × (oldAvg − target) ÷ (target − buyPx)
Breakeven move % = (avg ÷ marketPx − 1) × 100
  • Averaging down is only mathematically helpful if you genuinely believe the price will recover — it doesn't reduce risk per se, it increases position size.
  • Reverse mode: target must be strictly between buy price and current avg, else there's no solution.
