The Pattern Ledger — Automatic Seasonality & Pattern Analysis
"Mondays are always bad for this pair." "This stock always gaps up in December." Are those things actually true, or does it just feel true because you remember the times it happened and forget the times it didn't?The Pattern Ledger answers that with the data instead of your memory.What it finds automatically — no rule to write Day-of-week win rates — is a specific weekday actually stronger or weaker for this instrument, with real sample sizes attached Monthly seasonality — which calendar months have historically been strong or weak, across every year in your data Gap behavior — how often the instrument gaps at the open, and how often that gap actually fills same-session Streaks — average and longest winning/losing streaks, so five red days in a row doesn't feel like something's broken if that's actually normal for this instrument Why this is different from a subscription analytics platformTools that do this kind of statistical pattern analysis (Edgeful and similar) run $49-299/month as a subscription. This is the same category of analysis, one-time purchase, runs on your own machine.Honest about its limitsEvery stat comes with its sample size attached, and the tool flags it plainly when your dataset doesn't have enough history yet for a seasonality pattern to mean anything. This finds what already happened — it doesn't predict what happens next, and it won't pretend otherwise.Runs 100% locallyNo account, no subscription, no data sent anywhere.
