TSI — True Strength Index

What it does

Smooths momentum twice for a cleaner read of trend strength and direction around a zero line.

What happens

Recomputed once per candle from its wired source, incrementally (constant work per bar). It emits no value until the warmup period has passed; after that it produces a value every bar.

When to use

Momentum direction and zero-line crosses with less noise than raw momentum.

Gotchas

• Double smoothing adds lag — signals confirm later than faster oscillators.
