Common Questions

What is position sizing?

Position sizing sets trade quantity from planned account risk and stop distance.

Why does stop loss distance affect position size?

A wider stop risks more per unit, so the position must be smaller to keep total risk unchanged.

Should every trade risk the same amount?

No fixed percentage suits every trader. Use a consistent risk plan that fits your own limits.

Is this calculator suitable for all markets?

No. Forex, futures and some CFDs can require pip, tick, contract and currency conversion data.
