How to automatically preset amount of trading capital to use?

Hi all, let's say I'm a scalper and I want to day trade the QQQ.

According to my position size calculator, I can use all my trading capital if I set my stop loss to be very small (eg 0.05%).

Is there a way to set the stocks preset (in Global Configuration) so that IB uses all my capital for a trade?

I know you can preset the stop loss and take profit but it would be great if I didn't have to manually calculate how many shares to trade.

Thanks

 

Why don't you want to manually calculate how many shares to trade?

 

he’s probably trying to trade fast to capture ticks.

 

I imagine there are trade managers that can be purchased to auto calculate your positions based on your risk.

 

I assume you're using the GUI, right? If so... have you considered this?
