True strength

What does True strength measure?

A double-smoothed momentum gauge that keeps direction but sheds noise. Traders use its zero line and its turns rather than fixed thresholds.

How is True strength calculated?

Take the candle-to-candle price change, smooth it over 25 candles, then smooth it again over 13. Do the same to the SIZE of those changes (minus signs removed), and express the first as a percentage of the second.

Written by reading the engine’s real computation, not a textbook — where the two differ, the page describes what actually runs.

How do I use True strength in a bot?

In the builder, add an indicator of type tsi (parameters: long, default 25; short, default 13). Its value becomes an operand you can compare in any entry or exit rule. The engine grades the whole rule honestly: real fills, no look-ahead, half the history held back.
