Heikin Ashi Candles, Smoothing the Noise

[PTScalper]

How This Acts During Real Market Events

The 22:00 UTC Rollover: At 21:58, your baseline spread is 0.8 pips. Your dynamic limit is 2.4 pips. At 21:59, liquidity vanishes and the spread blows out to 7.0 pips. The price physically crosses your RR target, but currentSpread (7.0) > effectiveSpreadLimit (2.4). The bot blocks the execution. If price reverses during the rollover, your stop loss remains intact. If price stays at the target, the bot will instantly execute the scale-out at 22:05 when the spread compresses back down to 1.5 pips.

The High-Impact News Release (NFP / CPI): For an hour before NFP, the market dies. Your baseline spread shrinks to a pristine 0.3 pips. When the news hits, you want the bot to take profit immediately—but 0.3 pips * 3.0 means a limit of 0.9 pips, which is impossible during NFP execution. Because of the MinBaselineSpread (0.5) parameter, the math bottoms out at 1.5 pips (0.5 * 3). If the AbsoluteMaxSpread is 3.0, the dynamic filter allows the scale-out to fire up to 1.5 pips without throwing a hard API block, giving you the best chance of escaping the volatility.

Yeah that's the bit people miss. An HA close isn't a price you can actually get filled at, so any backtest that enters at the HA open is lying to you a little. I keep it on H1 for the trend read and do the actual entry and stop off normal candles on M5.

Good summary, Fairman. One caution for scalpers using Heikin Ashi: the displayed prices are averages, not real prices. The close of a Heikin Ashi candle is not where the market traded, so placing stops or measuring targets from the Heikin Ashi chart can be misleading by a few pips, which is a lot on a scalp. A common approach is to use Heikin Ashi only to read the trend and switch to the standard candles for the exact entry, stop and target levels.
