That's where position sizing comes in.
A 660-pip stop loss only looks "insane" if you're using the same fixed lot size on every trade. In reality, no stop loss distance is too wide once you understand proper risk management.
For example, if I’m only willing to lose $1,000 on this trade, I simply calculate the lot size so that if price hits that 660-pip stop, I lose exactly $1,000 — nothing more. That turns a wide stop into a perfectly controlled risk.
This is called risk-based position sizing. You decide the dollar amount you're comfortable losing, then size your position accordingly. That way, whether the stop is 100 pips or 1,000 pips, your account risk stays the same.
Once you get this, everything changes. It now becomes a game of win rate and percentage ratio.
