How it works

The quantity is set so that the loss, if the price reaches the stop, equals the share of capital you chose. Gaps, slippage and charges can make the actual loss larger.

Formula

Quantity = capital x risk% / |entry - stop|

Frequently asked questions

How is position size calculated?

Divide the amount you are willing to lose by the loss per share between entry and stop.

Does the stop loss guarantee the loss?

No. Prices can open beyond the stop, so the loss can be bigger.

Are charges included?

No; brokerage, taxes and fees add to the cost.
