Understanding Position Sizing Beyond 'X% Rule'

Many talk about the '1% rule' for risk, but true position sizing is more nuanced. It involves not just your risk tolerance per trade, but also the volatility of the asset and your actual stop-loss placement. For instance, risking 1% on $MXNJPY with a tight stop when it's been ranging 9.28-9.32 might mean a larger notional size than risking 1% on $USDTHB with a wider stop, even though both are 1% of your capital. The key is ensuring your capital risk remains consistent, regardless of the trade's specifics.

This is a great point. It's easy to oversimplify, but adjusting position size based on an asset's typical movements and where your stop needs to be is key to making that 1% risk truly mean 1% of your capital, rather than just a fixed number of shares.

This makes so much sense! So, if a stock is super volatile, even if my dollar risk is the same, my actual share count would be lower because my stop loss would naturally be wider? I'm still trying to get my head around how volatility and stop placement directly interact to determine the final share number.
