Let’s talk about position sizing.
Many trading resources recommend limiting the risk on any single trade to around 1%–2% of your total capital, though the right percentage varies from person to person.
To be honest, I hadn’t paid attention to this next point before: before opening a position, decide on three figures—the stop-loss price, how much you can afford to lose on the trade, and the position size implied by those two numbers.
On a related note: $BTC is trading at 81020.83, down 2.81% over 24 hours.
Leave more room for fluctuations when trading futures, so one sudden price swing doesn’t knock you out of your position.
