Pyramid Position Builder
RISK WARNING: this EA opens additional live market positions automatically as price moves. Shrinking each add's size caps how fast exposure grows, but it does not make the position risk-free - a full group that gives back its trailing stop distance in one move can still lose more than the base position alone would have. It never adds to a position that has moved against it. Confirm every input on a demo account before running it live. This is classic pyramiding, and it is deliberately different from the flat-size ScaleInManager already in this catalogue. Each add's size is InpBaseLots * InpAddSizeMultiplier raised to the power of the add's stage number, so with the default multiplier of 0.5 the first add is half the base, the second is a quarter, and so on - every add smaller than the one before it. That is the opposite of a martingale, where later additions would grow instead of shrink, and it means a losing reversal after several adds gives back proportionally less than an equal-size scale-in would. Once at least one add exists, every open ticket in the group has its stop trailed behind the current price by InpTrailStopPips on every scan. The trail only ever tightens - a ticket's stop never moves further from price - so the group's worst-case outcome improves monotonically as the pyramid grows, without needing a separate breakeven step. The base position is not opened by this EA - it is adopted. Open a position by hand, or with any other EA, tagged with InpMagicNumber, and this manager picks it up on its next scan. Notes and limitations - If adds already exist under InpMagicNumber when this EA is first attached (for example after a terminal restart), they are counted toward InpMaxAdds and InpMaxTotalLots on adoption rather than ignored, so the caps still hold going forward. - The trailing stop is a simple fixed pip distance behind current Bid or Ask, not an ATR or structure-based trail, and it is only applied once the group has grown beyond the base position. - This EA only manages one base position per magic number per symbol at a time. Running two unrelated positions under the same magic number on the same symbol will confuse which one it treats as the base. - It never closes the group itself - only stop-losses, take-profits, and the trader's own decisions end the trade.
