💡 Size always flows from risk, not from gut feel. With this position, hitting your stop loses exactly the planned risk amount — no surprises.
Works for any market: stocks (e.g. AAPL @ $190, stop $186), crypto (BTC @ $65,000, stop $63,500), futures, options premiums, anything quoted in price per unit.
