Pipsgrowth EX03025 Grid

Pipsgrowth EX03025 Grid is a counter-trend scalper that fires after intraday extremes, built on a custom Andean Oscillator (AOS) computed in-EA rather than pulled from an iCustom handle. The trade is fade-the-dip: long when the AOS Bull line crosses back up through its Signal while a recent bar in the lookback window has slipped below the running daily low, and the mirror image for shorts. The oscillator and the daily extremes are both rebuilt every new bar from raw price data, so the strategy's view of the market is rebuilt 288 times a day on M5 and never accumulates stale state from prior days.

The two AOS components, Bull and Bear, are calculated inside ComputeAndeanOscillator() over BuffSize = AosNCheck + DhlNCheck + 2 = 352 bars. The function maintains a running max of highs and a running min of lows through the lookback, then constructs Bull = close + alpha * (high_max - close) and Bear = close - alpha * (close - low_min), with alpha = 2 / (AosPeriod + 1) = 2/51. Both series are then EMA-smoothed in place with the same alpha, and a Signal line is the EMA of Bull at the faster alpha = 2 / (AosSignalPeriod + 1) = 2/10. The three output arrays are sized to 352 and indexed in series mode. There are no iCustom handles, no chart subwindow, and no companion indicator — the oscillator lives only in EA memory.

The entry engine in BuySignal() reads the crossover at bar 1: AOS_Bull[2] <= AOS_Signal[2] AND AOS_Bull[1] > AOS_Signal[1] — Bull turning up through Signal. The function then walks backward from bar 3 up to AosNCheck = 300 bars, looking for the most recent pivot where Bull was last below Bear and below Signal at the same close (a swing low in the oscillator). The bar where that pivot lands becomes j. From j forward through DhlNCheck = 50 bars, the engine checks whether any bar's high sat below the running daily low stored in DHL_L[i] while the AOS was still in bear configuration (Bull below Bear). When both conditions hold, a market buy is dispatched through ea.BuyOpen(). SellSignal() is the symmetric mirror, gated on Bear crossing up through Signal, a recent bar above the running daily high, and Bull above Bear at that bar.

Daily High/Low is built by ComputeDailyHighLow() walking the same 352 bars, resetting dayHigh and dayLow whenever the calendar day changes (compared through MqlDateTime). The arrays DHL_H[] and DHL_L[] are series-indexed. Because the running extremes include the current bar, the extreme-bar filter inside BuySignal()/SellSignal() is a stringent condition that selects only setups where the daily range has been violated by the bar's high/low relative to the running low/high — a deliberate guard against entering on shallow pullbacks.

SL and TP are calculated but, by default, not attached. BuySL(SLType=SL_SWING, SLLookback=7, SLDev=60) returns a swing-based stop with 60 points of allowed deviation, and TP = entry + TPCoef * |entry - SL| = 1.5R. Both are passed into ea.BuyOpen() along with IgnoreSL = true and IgnoreTP = true, so the framework does not attach them as order-level protection. The only mechanical exit is the trailing stop, applied every 30 seconds from OnTimer(). TrailingStopLevel = 50 (i.e. 50% of the framework's profit-distance basis) ratchets the stop behind the trade as it moves in favor. There is no time-based exit and no opposite-signal exit inside the entry functions — the trade runs until the trail closes it, the equity stop fires, or the grid basket closes.

The grid layer is off by default (Grid = false). When enabled, GridMaxLvl = 50 layers are allowed per side, GridVolMult = 1.1 scales each additional layer's lot, and GridTrailingStopLevel = 20% applies a separate, tighter trailing to the basket. With the grid off, the EA is a single-shot, no-SL, no-TP, trailing-only mean-reversion trade. With the grid on, the EA accumulates a recovery ladder up to 50 deep on each side, and the basket can survive deeper adverse moves before the equity stop triggers.

Pre-trade gating in OnTick() runs once per new bar (lastCandle is compared against iTime of the current bar). The gates in order are: OpenNewPos must be true, spread must be at or below SpreadLimit (default -1 disables the filter), margin level must be at or above MarginLimit = 300% if any position is open, and if Grid is on or MultipleOpenPos is off, the EA blocks new entries while a position is open. BuySignal() is tried first, then SellSignal() if the buy fails. There is no time-of-day filter, no day-of-week filter, and no session window — entries can fire on any bar that meets the conditions, including the Asian session or the NY rollover.

The news filter (News = false by default) is wired but inert. When toggled on, fetchCalendarFromYear(NewsStartYear) is called in OnInit() and the EA gates entries for NewsMinsBefore = 60 minutes before through NewsMinsAfter = 60 minutes after any event at NewsImportance = MEDIUM or higher. With News off, the EA fires on every qualifying bar regardless of macro calendar, which is a meaningful difference for traders running this on AUDUSD around RBA / AU CPI / China data.

The risk engine sizes each trade at Risk = 0.5% of equity per entry under RiskMode = RISK_DEFAULT, scaling the lot to the SL distance computed by BuySL. With IgnoreSL = true, the lot is sized to a stop distance the framework calculated but did not attach, so the actual per-trade dollar risk is the framework's interpretation of the swing stop. EquityDrawdownLimit = 0 disables the global equity stop; setting it to e.g. 20 engages ea.CheckForEquity() to flatten when equity drops 20% from peak. Slippage = 30 points is passed to the trade request. Magic 22203025 and the comment 'Psgrowth.com Expert_03025' identify the EA's own orders on the account.

This is a contrarian / mean-reversion EA, not a breakout despite the brief. The setup is 'AOS turns up, daily low was just violated, go long' — fade-the-dip. The combination of no per-trade SL, no per-trade TP, and trailing-only management means losers can run deep before the trail catches up, which is consistent with the VERY_HIGH risk level. On AUDUSD M5 with default settings, the EA produces a low-frequency signal stream (the daily-low-violation filter is exacting) and rides each trade for many bars. The grid option exists for traders who want to convert a single-shot mean-reversion into a martingale-style recovery, but the default config does not.

The expected backtest profile on AUDUSD M5 is sparse entries with mixed R-multiple outcomes. Winners can be substantial when the trail runs for an extended move, and losers can be small because the trail typically closes at a slight loss or breakeven if the setup fails quickly. The combination of contrarian entries and trailing-only management tends to produce equity curves that chop during directional days and trend during range days. With the grid enabled, the curve's drawdown profile shifts to depend on how deep adverse moves run and whether the equity stop is engaged before the basket recovers.
