- Copy the code and paste it into your page's HTML, a WordPress Custom HTML block, or your site builder's embed element.

Why we give these away
MarketPro is a trading signal and trading education app. The calculators exist because our signals carry explicit entry, stop and take-profit levels, and those are only useful if a trader can turn them into a position size. Letting other sites use the same tools costs us almost nothing and helps more traders size positions properly.
