Check out the new article: Did Your Scale Outs Actually Help? A Scale Out Value Analyzer in MQL5.
The article presents an MQL5 tool that tests whether scaling out improved results rather than only appearing disciplined. It reconstructs positions from closing-deal history and reprices the full volume at the first, last, and best exit rates actually achieved, producing a Value-Add Ratio, a Scale-Out Win Rate, and an Efficiency measure. A single-trade dependence check and a configurable A+ to F grade turn these into clear, decision-ready feedback.
A strategy report's net profit is the sum of every closing deal, already blended. It cannot separate "the market moved further after I sold the last piece" from "the market reversed right after I sold the first piece," because by the time the report is generated, both outcomes look identical: one number per position. A trader who scales out of every position and a trader who never does can show the same net profit for entirely different reasons, and the report will not tell them apart.
The gap is not a lack of data. MetaTrader already stores every closing deal separately, including the price and volume of each partial exit. The missing piece is a comparison: what this same position would have returned if the trader had NOT scaled, using only the exit prices the trader actually achieved. That comparison is what the rest of this article builds.
