Fractal Breakout EA
This is a published price-structure idea, offered here for study and as a template to adapt, not a guaranteed edge. A fractal marks a local high or low with two lower highs (or two higher lows) on each side of it, using the built-in iFractals() indicator - no external download required. The trap in this indicator specifically: a fractal is not known the instant the candidate bar forms. iFractals needs the two bars after it to close before the pattern is confirmed, so a fractal that structurally "happened" at bar shift 2 only stops repainting once bar shift 0 itself has closed - one full bar later than it looks from the chart. This EA reads iFractals at shift 2 on every new-bar event, which is the earliest point the value is stable, and only acts on values that changed since the last check. The most recent confirmed up-fractal and down-fractal are kept as a pair of breakout levels. A buy-stop sits above the up-fractal and a sell-stop below the down-fractal, each using the opposite fractal as the stop-loss reference - the logic being that if the level structurally on the other side of the range gets taken out, the breakout thesis for this pair has already failed. Whichever side fills first has the other cancelled immediately, and fractal updates pause entirely while a position from this EA is open. Notes and limitations - Needs both an up-fractal and a down-fractal confirmed at least once before either side arms - a brand new chart with no fractal history yet will show "none" in the Comment until both appear. - One position at a time, tracked by InpMagicNumber. Fractal updates pause while a position is open, so the levels shown afterwards will lag until the position closes and the next new bar re-evaluates them. - If the opposite fractal has already crossed to the wrong side of the entry (a very tight or unusual structure), that side is simply left unarmed rather than sent with an invalid stop. - Requires AutoTrading enabled; on MQL4 that is checked via IsTradeAllowed(), on MQL5 via TERMINAL_TRADE_ALLOWED plus ACCOUNT_TRADE_ALLOWED and ACCOUNT_TRADE_EXPERT. If trading is disabled the EA logs it and does not maintain the pending orders. - A published pattern, not a strategy with a documented statistical edge on any specific symbol - test on your own data before trusting it.
