Momentum Persistence System

"The trend is old, it must reverse soon" is a common instinct with no statistical grounding behind it unless someone actually measures how long runs on this specific symbol tend to last. This system does that measurement directly from the symbol's own closed-bar history rather than assuming a fixed number: it scans InpMeasurementBars of history, breaks the close-to- close direction sequence into consecutive same-direction runs, and averages their lengths into a single "measured persistence" figure in bars. A continuation trade is only opened while the CURRENT run (counted back from the last closed bar) is both at least InpMinRunBars long (some confirmation required) and still shorter than the measured persistence length - i.e. on the evidence gathered from this symbol's own history, a run this length has more often kept going than reversed. Once the current run reaches the measured length, the system stops opening new continuation trades in that direction; it is not betting against its own measurement by chasing an already-extended move. The measurement is not fixed at attach time - it is recomputed every InpRemeasureEveryBars closed bars, since a value baked in once would quietly stop matching the symbol as its volatility regime shifts over weeks or months. An open position is closed the moment the run actually breaks (a close prints against the held direction), independent of where price sits relative to its stop or target, since the persistence thesis for that trade is over the instant continuity breaks. Position sizing is risk-based off the symbol's own tick value and tick size, never a hardcoded contract size. Exit management runs through a ticket- collect-first loop scoped to this system's own magic number. Notes and limitations Runs are measured on close-to-close direction, a simple definition that ignores intrabar structure and wicks entirely - two very different-looking bars with the same net direction count identically. The measured persistence figure is a plain average of historical run lengths, not a percentile or confidence interval; it describes typical behaviour, not a guaranteed ceiling, and is only ever a description of the past InpMeasurementBars bars, not a forecast. Only one position per magic/symbol is held at a time. Grid, martingale and averaging are NOT used; every position is single, risk-sized and independently stopped.
