Hello,
I have this linecode for setting the lot amount:

double Lot = eq/bidBar.getOpen()/1000*prc/100;

which give not rounded lots amount (for example 0.0023 or 0.0452, etc.)

How can I have round lots amount (with a leverage 2)
for example
if equity=0.01053 lot= 0.02 (rounded equity*2)
if equity=0.01103 lot= 0.022
if equity=0.01199 lot= 0.022
if equity=0.01201 lot= 0.024

Do I have to use something like round.math() or something else?
Thank you

Hi,
Sorry for not answering for a long time. If you want to truncate a double number to 3 digits after comma, you need to multiple the number with 1000, convert a number to a long type, then divide the number with 1000 and convert to a double:

private double truncate(double x) {
   long y = (long) (x * 1000);
   return (double) y / 1000;
}

To calculate an order amount based on the account equity, please try the following code:

      double lot = truncate(account.getEquity())*2;
