Smart Break-Even and Partial Close - R-based trade manager - MetaTrader 5 için uzman

Smart Break-Even & Partial Close manages open positions opened by hand, from the phone app or by other Expert Advisors. It works in R multiples: 1R is the distance between the entry and the original stop loss, remembered the first time a stop is seen.

What it does, in order:

1. Partial close: at InpPartialAtR (default 2R) it closes InpPartialPercent (default 50%) of the volume, once per position. Volume is rounded to the symbol's lot step; if the position is too small to split, the step is skipped.

2. Break-even: at InpBreakEvenAtR (default 1R) the stop moves to entry plus InpBreakEvenOffset points, to cover spread and commission. Trades without a stop loss can use InpBreakEvenPoints instead.

3. Step trailing: from InpTrailStartR the stop trails InpTrailDistance points behind price and only moves in steps of InpTrailStep points.

Inputs:

- InpMagicFilter (-1): magic number to manage; -1 = all positions, 0 = manual trades only.

- InpAllSymbols (true): manage all symbols, or only the chart's symbol.

- InpBreakEvenAtR (1.0), InpBreakEvenPoints (0), InpBreakEvenOffset (20).

- InpPartialAtR (2.0), InpPartialPercent (50).

- InpTrailStartR (2.0), InpTrailDistance (300), InpTrailStep (100).

Design notes:

- A stop is modified only when the new level is better than the current one, and only if it respects the broker's minimum stop distance. This keeps the number of server requests low, which many prop firms check.

- The original risk and the partial-close flag are stored in terminal global variables, so a terminal or VPS restart does not reset the logic. Entries for closed positions are cleaned up every minute.

- Works on hedging and netting accounts and on any symbol and timeframe. Attach it to one chart.
