Pipsgrowth EX17001 Volatility

Pipsgrowth EX17001 Volatility Navigator is a mean-reversion EA built around the idea that sharp pushes beyond a 20-period Bollinger Band (2.0 standard deviation) rarely extend further when the 14-period RSI is simultaneously stretched. The strategy is delivered as a single-direction trade: a long fires when the last fully-closed candle closed below the lower Bollinger Band while RSI(14) printed under the 30 oversold threshold, and a short fires on the mirror setup — close above the upper band with RSI(14) above 70. The decision is anchored on the closed bar (shift = 1), so live ticks never re-arm an entry that has already printed. The 12-layer scaffold that wraps the signal consists of REGIME, SIGNAL, ENTRY, CONFIRM, NO-TRADE, CAPITAL CAP, RISK, SIZING, MANAGE, EXIT, SCALING, and OnTester — each implemented as a separate function in the source so a reviewer can audit any layer in isolation.

The regime gate is the part that defines this EA's character. DetectRegime() builds ATR and Bollinger-width percentile ranks over a 50-bar lookback and reads ADX(14) at the current bar, then returns one of seven states: STRONGTREND, WEAKTREND, RANGE, BREAKOUT, COMPRESS, EXPAND, or CHOPPY. The mean-reversion entry is only allowed when the regime is RANGE, COMPRESS, or WEAKTREND — regimes where stretched oscillators tend to snap back. STRONGTREND and CHOPPY are explicitly rejected by NoTradeReason() before the signal is even read, and a secondary ADX hard-cap (InpRegimeADXMax = 35) blocks entry when directional strength becomes hostile to mean-reversion. The HTF confirm (a 50-period EMA on a higher timeframe, default H1) only has to agree with the signal direction to be marked true; if it disagrees, the confirm fails and the trade is dropped — that is why a long on M5 against a clean H1 downtrend will not fire.

Risk is sized off the effective capital. EffectiveCapital() returns the account equity but floors it at InpCapitalCapAmount if a positive cap is configured, and entry is blocked entirely when equity falls below InpCapitalCapFloor (50 dollars). InpRiskPercent defaults to 0.5 percent of effective capital per trade. The stop distance is ATR(14) multiplied by InpATRMultiplier (default 1.5), and the take-profit is the same distance multiplied by InpRR (default 2.0) — a 1:2 reward-to-risk structure. Lot size is computed in CalcLots() using the symbol's tick value and tick size so that a 0.5 percent risk per trade corresponds to a stop at exactly ATR×1.5 on XAUUSD. The size is then rounded to the broker's lot step and clamped between the symbol's lot min and lot max. Two real-money loss caps sit on top of this sizing: a 3 percent daily loss limit and a 6 percent weekly loss limit, both checked from realized PnL since midnight and Monday 00:00 server time respectively, and both feed the NoTradeReason() gate.

The management layer is the part that tends to do most of the work in live conditions. ManagePosition() runs on every tick, not just on new bars. It tracks the position's R-multiple — current price distance from entry divided by the original stop distance — and applies four distinct protections in sequence. The first is a momentum-decay exit: if the trade goes against the position by 0.5R or more, the position is closed immediately. The second is a break-even move: once the trade reaches InpBETriggerR (default 1.0R), the stop is ratcheted to entry + 0.10 × ATR, locking in scratch-plus. The third is an ATR trailing stop that activates at 0.80R and trails at 2.0 × ATR behind the bid/ask. The fourth is a partial take-profit: at 1.0R, 50 percent of the position is closed, leaving half the size to run under the trailing stop. All four moves respect the symbol's SYMBOL_TRADE_STOPS_LEVEL and use TryModify_EX17001 / TryClosePartial_EX17001, each a 3-retry scaffold that sleeps 200ms on requotes or price-changed returns. A hard time stop closes any trade older than 240 bars in the same function.

The confirm and no-trade stack adds a session window and spread cap. ConfirmFilters() reads the server hour and only passes between hour 7 and hour 20 (London to New York close) by default — the code defines DEF_SESSION_START_HR and DEF_SESSION_END_HR as tunable constants but leaves the inputs unexposed, so the session is hard-coded unless a developer recycles the source. The spread gate is configurable: InpMaxSpreadPoints defaults to 30 points and is also fed into the trade request's deviation parameter. A weekend gate blocks entries on Saturday, Sunday, and on Friday after 21:00 server time. A 12-bar cooldown is triggered after any closed losing deal — its bar timestamp is recorded in g_lastLossBarT and checked on every new-bar attempt via iBarShift. The InpDryRun input defaults to true, which means new installs will only print [DRYRUN] log lines until the operator explicitly flips it.

OnTester is the optimization objective: it returns (STAT_PROFIT × STAT_PROFIT_FACTOR) / (1 + STAT_BALANCE_DD), only after at least 30 trades. This multiplies raw profit and profit factor and divides by drawdown — a strategy that has a high profit factor and modest drawdown scores well, while a high-profit but high-DD combination gets penalized.

This EA works best on XAUUSD M5 where the ATR provides enough room to avoid the minimum-stop rejection and the Bollinger extremes are frequent enough to trade. M15 and H1 work as well, but the cadence drops sharply. Because the strategy is a pure mean-reversion, it should be paired with an ECN or low-spread account — the 30-point spread cap is the boundary. Do not run it during NFP, FOMC, or rate-decision events; the regime filter cannot react fast enough to a volatility expansion. Backtesting in the Strategy Tester should use 'Every tick based on real ticks' with a quality of 99 percent data to capture the spread behavior accurately. The capital-cap input should be set to roughly twice the planned max drawdown — that prevents the EA from over-sizing after a winning streak.
