Pipsgrowth EX07018 MA

Pipsgrowth EX07018 MA opens long or short positions on XAUUSD M5 whenever a 10-period EMA crosses a 20-period EMA, and runs two risk locks (breakeven and a ratchet-style trailing stop) to keep the result of every trade from going negative once the price has moved far enough. The crossover itself is detected on a freshly closed bar — IsNewBar() compares the current bar's open time against g_lastCandle and only returns true once, so each crossover fires exactly one order request and signal-flicker on the same bar is impossible. The first EMA is built with iMA(_Symbol, _Period, 10, 0, MODE_EMA, PRICE_CLOSE); the second is the same call with period 20. Both are released in OnDeinit().

The entry pipeline is short. After IsNewBar() flips, OnTick() calls IsWithinTradingSession(), then IsSpreadOK(), then reads two bars of each EMA. A buy triggers when fast[1] > slow[1] and the previous bar had fast[2] <= slow[2] — the classic bullish cross. A sell is the mirror. The order is then sent with trade.Buy(lot, _Symbol, ask, sl, tp, InpTradeComment) or trade.Sell(...) with sl = ask/bid ± 500 points and tp = ask/bid ∓ 1500 points. That is a hard-coded 1:3 risk-reward against the 500-point stop, which is the most asymmetric TP target in the EX07xxx MA family — most siblings target 1:1 or 1:1.5.

Position sizing in CalculateLotSize(slPoints) is a five-step routine. If InpRiskPercent is greater than zero, it pulls AccountInfoDouble(ACCOUNT_BALANCE), multiplies by InpRiskPercent / 100, divides by the per-lot loss at the requested stop, snaps the result down to the nearest SYMBOL_VOLUME_STEP, clamps to [minLot, maxLot], then calls OrderCalcMargin. If the resulting margin would consume more than 80% of ACCOUNT_MARGIN_FREE, the lot is scaled back proportionally. The final number is also capped against InpMaxLotSize (1.0 by default), so a runaway balance can never push the position size past the user-set ceiling. If InpRiskPercent is set to 0, the function falls back to InpFixedLot (0.01) — the same fallback the function uses whenever tick value, tick size, or _Point is zero.

Once a position is open, two management routines run on every tick, ahead of the new-bar logic. ManageBreakeven() waits for a long position to be InpBEStart (200) points in the money and the current stop to be below the open price, then it tries to move the stop to open + InpBEProfit * _Point (entry + 50 points). Sells are mirrored. ManageTrailingStop() then waits for a further 100 points of profit (300 points total from entry) and lifts the stop to bid - InpTrailDistance * _Point (current bid minus 200 points), provided the new stop is above both the existing stop and the open price. The two together produce a three-stage ratchet: a breakeven lock at +200, a trailing stop kick-in at +300, and a continued 200-point trail behind price as it advances. The same three retries-and-200ms-loop pattern is used by TryClose_EX07018, TryClosePartial_EX07018, and TryModify_EX07018 against REQUOTE, TIMEOUT, PRICE_OFF, and PRICE_CHANGED retcodes — the close/partial routines wait 200 ms between attempts, the modify routine waits 100 ms and only retries on REQUOTE/TIMEOUT.

The session filter in IsWithinTradingSession() is built as two independent windows, not one continuous block. Session 1 covers server hours 8 to 12 (the open of the London session, when gold typically makes its first directional move of the European day). Session 2 covers server hours 14 to 18 (NY pre-open and the first half of the US session, the second most active gold window). Each session can be toggled independently with InpEnableSession1 and InpEnableSession2. The function reads the broker's TimeCurrent() directly — there is no GMT auto-detection, so the meaning of "hour 8" depends entirely on the broker's server clock. Spread protection in IsSpreadOK() measures the live ask-bid gap in points and rejects entries beyond InpMaxSpread (200 by default), which is essential on XAUUSD where spreads can balloon during off-hours or news events.

The optional safe-pyramid mode (InpEnablePyramid = false by default) is the most subtle piece of logic in the EA. IsPyramidSafe() does three things. First, it returns false immediately if pyramiding is off or if the open count is already at InpMaxPyramidLevels (3). Second, it scans all open positions on the symbol/magic. Third, for each existing position it checks the current stop-loss against the open price: for a buy, the SL must be greater than openPrice + InpMinSLProfit * _Point; for a sell, the SL must be less than openPrice - InpMinSLProfit * _Point (or zero). The semantic is that the existing position's stop has already been lifted to at least 150 points in profit — meaning the breakeven or trailing routine has already kicked in. This means you cannot pyramid into a fresh, unprotected position. With both pyramid and the management ratchets active, a strong trending gold day could build up to three entries on the same side, each with progressively tighter protection.

The 12-layer label in the file header is aspirational. The code does not implement a regime classifier, a higher-timeframe filter, ATR, ADX, RSI, Bollinger bands, news gating, a daily loss cap, an equity floor, a time stop, a partial-close path (the TryClosePartial_EX07018 function exists but is never called from OnTick), or an OnTester fitness function. What it does implement is a clean 10/20 crossover with two management ratchets, two session windows, a spread filter, a margin-aware lot sizer, and an opt-in pyramid that only adds when prior positions are already protected. The simplicity is the point: this is a small, readable, single-purpose EA that does one thing mechanically, and traders who want a regime filter, an HTF bias, or a news guard should layer them in themselves or pick a different EX07xxx sibling.

The default config is 1% risk per trade, 0.01 lot floor, 1.0 lot ceiling, 500-point stop, 1500-point take-profit, BE at +200 with +50 lock, trail at +300 with 200-point distance, both sessions on, spread cap 200 points, pyramid off. The EA identifies its orders with magic number 22207018 and the comment string Psgrowth.com Expert_07018.
