Abstract: { "name": "vilas_rolling_three_sliding_return_reversal", "source": "NSE India / algorithmic trading literature on rolling windows of cumulative return as mean-reversion trigger", "type": "filter_flag", "rule": "Enter short when the rolling 3-bar sum of log returns (close/close) is > +1.8 sigma above its own 20-bar mean of rolling sums, and current close is below the midpoint of the prior bar's range.", "pseudocode": "ret = log(c / c.shift(1)); roll3 = ret.rolling(3).sum(); mean20 = roll3.rolling(20).mean(); std20 = roll3.rolling(20).std(); cond1 = roll3 > (mean20 + 1.8*std20); cond2 = c < ( (h.shift(1)+l.shift(1))/2 ); entry = cond1 & cond2", "why_it_works": "Extreme short-term return clustering statistically reverts in low-liquidity regimes, and the midpoint rejection adds a microstructure tilt against the momentum blow-off." } Author: Andrew Stewart Caldin, Independent Researcher, UK.
