The math of extremes: how algo levels are computed
Video in Russian “Математика экстремумов”, 17 October 2026, 17:29.
What the video is about
The video explains the algo level calculation in detail: a day runs from 18:00 to 18:00 New York, the opening price is taken as zero, and for every fifteen-minute candle of all days of history the high and low are measured in percent.
Quantiles are computed from these arrays: for example, the 90% level is the deviation above which a candle's high was found in only 10% of cases; the same is computed from the open of the candle itself, the hour and four hours.
New filters are shown (weeks of history — up to 245, months, weekdays) and personal settings are compared with the reference; the author explains how he uses moves beyond the deviation norm together with liquidity levels. The video is in Russian.
Key claims
- A BIASMACHINE day runs from 18:00 to 18:00 New York: at 18:00, after the 17:00–18:00 technical break, the Chicago Mercantile Exchange (CME) opens — one of the few sources of verifiable index volumes.
- The day's opening price is taken as a conditional zero; for every fifteen-minute candle of every day its high and low are recorded in percent.
- Levels 50, 60, 70, 80 and 90% are the shares of candles whose high did not exceed the given deviation; above the 90% level price was found in only 10% of cases.
- Deviations are computed both from the day open and from the candle's own open; an algo level is the deviation norm from the candle open.
- The reference algorithm has four deviation levels: hourly and four-hour samples, each with fifteen-minute ones inside; marks 25, 50, 75 and 100% show several zones triggering at once.
- The filters let you choose the number of weeks of history — up to 245 weeks on the recording day (data as of 17 October 2026).
- To repeat the calculation, the hardest parts are data normalisation, clock changes and gaps in the data.

Questions about the video
What is an algo level?
The norm of price deviation from an interval's open — a candle, an hour or four hours — computed over all days of history for that time and asset. The 90% level is a deviation price exceeded in only 10% of cases.
Why does the day start at 18:00 New York?
At 18:00, after the technical break, the Chicago Mercantile Exchange (CME) opens — one of the few sources of verifiable index volumes; BIASMACHINE aligns with it.
Does crossing an algo level guarantee a reversal?
No. Crossing the norm only means such a deviation was rare. The author uses it together with liquidity levels and other factors, not as a forecast.
How to read the numbers
Numbers are given as stated in the video on the recording date, 17 October 2026. After Research studies are recomputed they may differ.
Historical frequencies are not individual investment advice and do not guarantee repetition. Hypothetical results do not reflect real trading (CFTC Rule 4.41 principle).
