Understanding Position Sizing: More Than Just 'How Much'

Hey everyone, been diving deeper into risk management lately, and wanted to quickly highlight something that's really clicked for me: position sizing. It's often simplified to just figuring out how many shares or units you can buy, but it's fundamentally about managing your risk per trade, not just the notional value of your trade.

Think about it: if you always risk, say, 1% of your total capital per trade, regardless of the asset, you're building a consistent foundation. For example, if you have a $10,000 account and want to risk $100 (1%) on a trade, and your stop-loss for $GOOGL is set at $330 while the entry is $337.39, your per-share risk is $7.39. This means you can buy roughly 13 shares ($100 / $7.39 per share). The current price is $337.39, but that's irrelevant to the risk calculation beyond setting your stop. The same logic applies whether you're trading $BTC or $BRL. It really changes how you look at opportunities, moving from "can I afford to buy this?" to "how much of this can I risk?" – a subtle but huge mental shift. I'm curious how others approach this, especially in volatile markets.
