DCA Safety Order Calculator - Capital Needed for Martingale Setups
Safety orders with volume multipliers consume capital geometrically. Know the total - and the true average entry - before the market does.

How to read it
Total required capital is the base order plus the geometric sum of safety orders. The deeper the deviation stack reaches, the lower your average entry - but a move beyond the last safety order leaves the full position underwater with no dry powder. The average entry shown is the true, quantity-weighted average (total USD / total coins) - the number your take-profit actually applies to, not the naive arithmetic mean. Conservative setups use small multipliers (1.2-1.5x) and enough orders to cover the asset's typical drawdown. Martingale sizing is the classic DCA bot failure mode - read the guide.
Model and assumptions
Safety order n triggers at the summed deviation dev x stepScale^(n-1) below entry and sizes at SO size x volumeScale^(n-1) - the 3Commas convention with an independent safety order size, not the old base-order shortcut. Fees are not included in the table; they shift the take-profit target by roughly the round-trip fee percentage.
