The Weekend Gap Statistics & Distribution Analyzer is a purely analytical MQL5 indicator designed to evaluate the historical behavior of weekend price gaps. It scans chart data to calculate gap closure rates and measures the adverse excursion (drawdown) experienced before a gap successfully closes. By providing statistical distributions—including the 70th and 90th percentiles of adverse heat—this tool enables traders to make data-driven decisions. It moves beyond simple averages, allowing traders to properly assess risk, filter out low-probability instruments, and optimize stop-loss placement when fading weekend gaps.
