I have this strategy and when I calculate the lot size with this formula, it gives me error.

  "Lot = equity * CoefficientRisk/100000"



Can you help? I want the machine to calculate the lots in this way
  "Lot = equity * CoefficientRisk/100000"

the error is
/ ---------- 24/07/2012 11:15:46
/ / 7/24/2012 11:15:46 equity can not be resolved
/ / 24/07/2012 11:15:46 ^ ^ ^ ^ ^ ^
/ / 07.24.2012 11:15:46 * CoefficientRisk/100000 amount = equity;

thanks for support

Add an IAccount field and assign it in the onStart:

private IAccount account;
public void onStart(IContext context) throws JFException {
    this.account = context.getAccount();

Then calculate the amount in the following way:

      double amount = this.account.getEquity() * CoefficientRisk/100000 ;

Mind to replace the this.amount (which is the global field amount) with amount (which will be the method-local variable).
In order to avoid such mistakes already before the compilation, consider programming your strategies in an IDE, e.g. Eclipse:
