💡 Size the trade from your stop — not from how much you want to make. Your risk stays fixed (a small % of the account); the position size changes every trade to keep that dollar risk constant. Wide stop → smaller position. Tight stop → bigger position. Same risk either way. That's the habit that survives losing streaks.

Position sizing, explained

How is position size calculated?

Position size = (account × risk %) ÷ (distance from entry to stop). Example: a $1,000 account risking 1% ($10), with a stop $16.56 below a $1,786.56 entry, gives 10 ÷ 16.56 = 0.60 units — a position worth about $1,079. If price hits your stop, you lose exactly your planned $10.

How much should I risk per trade?

Most professionals risk a small, fixed percentage — commonly 1% (sometimes up to 2%) of the account per trade. That keeps any single loss survivable and emotionally quiet, so you don't panic or move your stop. Risk is of the account, not the position.

Why does my position size change every trade?

Because your risk is fixed but your stop distance varies. A trade with a wide stop needs a smaller position to keep the dollar risk the same; a tight stop allows a bigger position. The calculator handles that automatically — you just keep the risk % constant.

Does this work for forex and stocks too?

Yes. The units returned are "how many of the instrument" — coins for crypto, shares for stocks, or units of the base currency for forex (divide by your lot size to get lots). The risk logic is identical across all markets. More on this in our position sizing guide.
