Entry Price Improver
Waiting for a small pullback before entering at market is a reasonable way to shave a few points off the fill, but an unbounded wait has an unbounded downside: if price never pulls back, the signal is silently missed altogether, which is a strictly worse outcome than the small amount of slippage the wait was trying to avoid in the first place. This header bounds the wait explicitly: arm it with the signal price, a pullback distance in pips, and a maximum wait in seconds, and it reports either "pullback reached, enter now" or "timeout reached, enter now anyway" - it never reports neither and leaves the signal hanging forever. The header is split into a pure decision function and a separate action function, the same split this catalogue's other trade-management headers use. EpiEvaluate() reads the current state, a caller-supplied price and a caller-supplied time and returns a decision code without sending anything - which means it can be driven with synthetic price/time values for testing, exactly as the demo does, without needing to wait on live ticks or risk a real order. EpiFireMarketEntry() is the separate, thin wrapper around OrderSend that actually enters, called only once EpiEvaluate has returned one of the two FIRE codes. Notes and limitations - The wait is time-bounded (seconds via TimeCurrent()), not bar-bounded. A bar-count cap can be built on top by comparing Bars/iBars() at Arm() time against the current count instead of calling EpiEvaluate with a TimeCurrent()-derived nowTime - the pure decision function does not care which clock the caller uses, since both the armed timestamp and the "now" value are supplied by the caller, not read internally. - EpiFireMarketEntry() sends a real OrderSend - this is the one acting function in the header. Only call it from the branch that already checked EpiEvaluate's return value. - Only one wait can be tracked per SEntryImproverState instance; track an array of states if more than one signal can be pending improvement at once. - No retry logic around EpiFireMarketEntry() itself - if the send fails (requote, off quotes, trade context busy), the caller's own error handling decides what happens next. This header only decided WHEN to attempt the entry, not how to recover if the attempt fails.
