Pipsgrowth EX17024 Volatility

Pipsgrowth EX17024 is a band-breakout EA that reads a smooth midline from a 10-period EMA on close, lays a ±0.85×ATR(14) envelope around it, and waits for a strong-bodied candle to punch through the envelope on the side that agrees with the slope of the midline and with the trend of a higher-timeframe EMA(50). The midline is labelled in the source as a "Gaussian" but is technically a standard exponential moving average — the label is a brand choice, the math is EMA. The EA runs all of its decisions on a single tick handler; it does not maintain state between bars beyond the cached values pulled from the indicator handles, so the OnTick routine stays tight and predictable.

The trade stack is intentionally narrow: three indicator handles, three working buffers, and a single CTrade object. The first handle is iMA(_Symbol, g_Timeframe, 10, 0, MODE_EMA, PRICE_CLOSE), which feeds the midline and the upper/lower bands. The second handle is iATR(_Symbol, g_Timeframe, 14), which scales the envelope width and gates entries against the AutoTuneFilters() floor. The third handle is iMA(_Symbol, g_TrendFilterTF, 50, 0, MODE_EMA, PRICE_CLOSE), where g_TrendFilterTF defaults to H4 — the higher-timeframe trend filter that the entry logic uses to confirm direction. All three handles are created in OnInit() and validated together; if any returns INVALID_HANDLE, the EA refuses to start with INIT_FAILED.

Entries are gated by a stack of conditions that all have to agree on the same tick. The candle-strength check requires the body of the most recent bar to be at least 60% of its full size (StrongCandleBodyRatio input), filtering out dojis and pin bars that lack conviction. The 2-bar inside-then-outside check requires pricePrev and pricePrev2 to have closed on the inside of the band while the current bar closes outside — a deliberate anti-whipsaw gate that prevents the EA from entering on the first touch. The slope check requires the current midline value to be either above or below the previous bar's midline value, depending on direction. The break-distance check requires the gap between price and the midline to exceed 0.3×ATR, which rules out marginal grazes. The HTF filter requires price to be on the same side of the H4 EMA(50) as the trade direction. Only when all five gates fire together does the EA fire a Buy or Sell through the CTrade object.

Pre-trade risk gates run before any entry is permitted. CheckMaxDrawdown() compares the floating equity against the balance and refuses to trade if the drawdown exceeds MaxDrawdownPercent (10% by default). The ATR floor comes from AutoTuneFilters(), which samples the current spread and decides whether the symbol behaves like a 4-decimal forex pair (pipFactor 0.0001) or a 2-decimal metals pair (pipFactor 0.01), then sets minATR to 3× that factor; the entry is suppressed when current ATR is below the floor. The position-count gate allows up to MaxOpenTrades (5 by default, but OneTradeOnly=true default restricts to a single position). The profitability gate, when AllowOnlyProfitableAdditions is enabled, requires every currently open position on the symbol to be sitting on at least MinProfitPerTradeToAdd ($5) of unrealized profit before a new entry is allowed — a conviction filter that keeps the EA from scaling into a losing basket.

Exits are driven by two mechanisms that work in parallel. The first is a fixed take-profit at FixedTP_Points (160 points by default) and an initial stop-loss at InitialSL_Points (100 points), set on entry. With gold quoted to 2 decimals the defaults map to a 1.6:1 reward-to-risk geometry on the initial brackets. The second is the Gaussian-cross exit, controlled by EnableGaussianExit. When the buffer multiplier ExitBufferATRMultiplier is set to zero, the EA closes the trade the moment price crosses back through the midline. When the buffer is non-zero (0.2×ATR by default), the exit level is shifted by that buffer — buys close only when price dips below midline minus 0.2×ATR, sells close only when price rallies above midline plus 0.2×ATR. The buffer is the practical way to avoid being shaken out by a marginal cross that immediately reverses.

The dynamic lock-profit ratchet is the third exit arm. EnableDynamicLockProfit walks the position's floating profit and computes how many $2 steps (LockProfitEvery_X_Dollars, default $2) of profit have been banked, then translates that dollar count into a price distance using the symbol's tick value, tick size, and current position volume. The new stop is set to entry plus that distance for buys, entry minus that distance for sells, minus a $1 buffer (LockMinusBuffer). The ratchet only ever moves the stop forward, never backward — the comparison newSL > sl for buys and newSL < sl for sells guarantees monotonic protection. The result is that once a trade has earned $2 of profit, the stop jumps to entry + $1; at $4 of profit, it jumps to entry + $3; and so on, with the floor rising in lockstep with the unrealized P&L.

Position-management execution goes through two wrapper functions, TryClose_EX17024 and TryModify_EX17024, both of which retry up to three times on requote, timeout, price-changed, and price-off retcodes, with a 200ms sleep between close attempts and a 100ms sleep between modify attempts. Any retcode outside that list breaks the retry loop and leaves the modification for the next tick. The wrappers are duplicated for symbol-based and ticket-based invocation; both paths are present because some calls in the EA use the symbol string and others use the position ticket.

Risk profile and runtime expectations: with default 0.1-lot entries, the EA can hold up to 5 concurrent positions on a single symbol, although the OneTradeOnly flag collapses that to one. The 10% drawdown cap combined with the 160-point fixed TP and 100-point initial SL means that a worst-case basket of 5 trades against the EA on a single symbol would be approximately 500 points of initial stop, or 0.5% of a 0.01-lot-per-point account. The ratchet then protects any profitable leg. On a $1,000 starting balance with 0.1 lots on gold, one losing basket consumes 1.0% of the account; the 10% drawdown gate triggers after roughly 10 such baskets, which is a generous safety margin for a single-symbol strategy. The EA was built and tested for XAUUSD on M5, but the input group includes a portable Timeframe knob and a TrendFilterTF knob that lets it run on FX majors and on H1 if you prefer a slower cadence. The H4 trend filter is the constant that keeps entries aligned with the dominant higher-timeframe direction regardless of the trading timeframe chosen.
