Position sizing

Hi Developer,

I want to calculate lot size to trade.

I will put 2 line on chart for entry and stoploss.

in the script or indicator, I will input:

1. trade is Buy or Sell

2. dollar value of maximum loss.

The script will then return the lot size for trade to make sure that if Stoploss is hit, the loss is the maximum dollar value.

There will be a option for me to let the script to place limit/stop order with these entry/sl information.

Please let me know if you can help.

Thanks

HHC
