Scripts/EA for opening manual trades by account size/risk %

Hi

Is there a script or EA that can automatically open trades with the lot size based on account size/risk %, to save having to make the calculation manually or using an online calc? I've had a look around but can't find anything. It seems very obviously useful so I'm sure it must be out there somewhere.

For example, I pull the EA onto the chart. Enter Risk '1%', Action 'Buy', stoploss pips '50', and it opens an order of the correct lot size for these settings?

Thanks

David
