Pipsgrowth EX16071 Trend

Pipsgrowth EX16071 Trend is a mean-reversion EA built around a homemade Bollinger envelope, not a trend-follower despite the family label. The source file Pipsgrowth_com_EX16071.mq5 constructs the bands in code: it loads iMA(symbol, PERIOD_CURRENT, MA_period=20, 0, MODE_SMA, PRICE_CLOSE) and a parallel iStdDev(symbol, PERIOD_CURRENT, MA_period=20, 0, MODE_SMA, PRICE_CLOSE), then treats the envelope as MA ± 2 × STDV. A 14-period iRSI provides the momentum filter. The three handles (handle_iMA_M5, handle_iSTDV_M5, handle_iRSI_M5) are all created against PERIOD_CURRENT, so the EA adapts to whatever chart timeframe you attach it to.

The signal engine fires only on a fresh bar. On the first tick of each new bar, OnTick snapshots iMAGet, iSTDVGet, and iRSIGet at indices 0 and 1 — that is, the just-completed bar and the bar before it. A long entry requires four conditions in concert: the previous bar's close finished below the lower band (Previous_Close < MA_1 - 2*STDV_1), the current bar's close has crept back inside or above that lower band (Current_Close >= MA_0 - 2*STDV_0), the RSI on the previous bar was below 30, and the current RSI is at or above 30. The RSI condition is a true cross, not a threshold — the bar that triggered the band re-entry must coincide with momentum turning up from oversold. The short side is the exact mirror at the upper band, with RSI crossing down through 70.

If the conditions are met, the EA refreshes quotes, then computes my_SL = Ask - STDV_0 and my_TP = Ask + 2*STDV_0 for longs (and +STDV_0 / -2*STDV_0 for shorts). The risk:reward ratio is hard-coded at 1:2 measured against the live one-standard-deviation distance. m_trade.CheckVolume validates the order against the broker's lot constraints before m_trade.Buy or m_trade.Sell is dispatched with magic 22216071. Lot size is fixed at my_lot, default 1.0 — there is no balance-percent, no risk-percent, no dynamic sizing, no scaling-in, and no martingale. The TryClose_EX16071, TryClosePartial_EX16071, and TryModify_EX16071 helpers exist in the source but the entry path does not call any of them.

Once a position is open, the OnTick loop performs a single protective task: it watches the current bar's close and, if a long's close reaches or exceeds the upper band (Current_Close >= MA_0 + 2*STDV_0), it calls TryClose_EX16071(ticket) to force-exit; shorts get the same treatment on the lower band. This is the EA's main safety net for trades that, despite the entry trigger, refuse to mean-revert. There is no trailing stop, no break-even ratchet, no partial close, no time-based exit, and no equity stop. The static SL and TP submitted with the original order are the only protective levels until the opposite band takes over.

The risk profile is dominated by the band width itself. Because the SL is exactly one STDV and the TP is two STDV, the trade is a coin-flip on whether the band touch leads to a true reversal or a continuation. When a strong directional day pushes XAUUSD through the lower band and keeps going, the EA's my_lot = 1.0 plus a 1-STDV stop on M5 can give back real money before either the SL or the upper-band close fires. Backtesters should pay particular attention to the loss-cluster periods around scheduled high-impact news, where Bollinger mean-reversion has the worst historical hit rate.

The header advertises a "12 layers: REGIME, SIGNAL, ENTRY, CONFIRM, NO-TRADE, CAPITAL CAP, RISK, SIZING, MANAGE, EXIT, SCALING, OnTester" stack, but the actual implementation is much leaner. There is no OnTester, no regime classifier, no session filter, no news filter, no max-spread gate, no max-open-positions limit, no daily-P&L breaker, no equity floor, no consecutive-loss cooldown, and no scaling logic. The EA will fire on every qualified signal as long as the broker is open. Treat the header's 12-layer claim as a family-level template, not as a feature list for this specific file.

There is one hard prerequisite that overrides everything else: the IsHedging() check inside OnInit returns INIT_FAILED on netting accounts. The account must be configured for ACCOUNT_MARGIN_MODE_RETAIL_HEDGING. Netting or exchange-style accounts will not load the EA at all — Print("Hedging only!") fires and initialization aborts before any indicator handle is created. The 3/5-digit adjustment in m_adjusted_point (multiplier of 10 for 3- or 5-digit symbols, otherwise 1) is the only broker-specific code path beyond the lot validation.

The seven input parameters split across three groups. Identity carries the magic number and trade comment; Trade Settings holds the single my_lot value; Indicators exposes MA_period, RSI_period, RSI_overbought, and RSI_oversold. There are no inputs for SL distance, TP distance, session windows, max spread, or position count — those are all hard-coded in the OnTick body. The XAUUSD default on the PipsGrowth listing reflects the file's intended volatility regime, but the brief in the header calls the EA "portable" across FX majors and other metals. The signal logic is symbol-agnostic, so the same code should fire on EURUSD or XAGUSD with no recompilation, provided the broker's spread and commission don't eat the 1:2 structure.

Traders who want to extend the file have a clean starting point. The two natural customisations are: (a) replacing the fixed my_lot with a balance-percent calculation referencing AccountInfoDouble(ACCOUNT_BALANCE) and the STDV-based stop distance, and (b) adding a max-spread input and gating the entry call on m_symbol.Spread() < MaxSpreadPoints. The opposite-band stopout logic in the position-management loop is worth keeping as-is — it is the only feature that prevents an open position from drifting into a multi-day adverse excursion without an exit.

A short note on what to expect in the MT5 Strategy Tester. With the default inputs, expect a high trade frequency on M5 (the band cross on a 20-period envelope is a frequent event in chop), an equity curve that is sensitive to spread assumptions (a 30-point XAUUSD spread will compress the 1:2 RR noticeably), and infrequent but occasionally sharp drawdowns during trend days when the lower-band bounce fails to materialise. The backtest is honest about the strategy's nature: a scalping-style mean-reversion, not a trend capture. Run the tester across at least three different volatility regimes before sizing live capital.
