Tiered (or dynamic) position sizing adjusts how much you commit per trade according to a signal rather than using one fixed size. A weight multiplier is applied when an indicator is above or below a threshold — for example, trade smaller when volatility (ATR) is high, or larger when a trend filter is strongly aligned.
It lets a single strategy press its best conditions and tread carefully in its worst ones, without changing the entry logic. As with all sizing, it should sit under a hard maximum-position cap so a tier can never produce an oversized trade.
Example
A strategy uses 100% of its base size when ADX > 25 (clear trend) and only 50% when ADX < 20 (chop).
