Created September 13, 2013 13:17

This simple script determines whether a new trade is viable according to the current level of portfolio risk. It does NOT take into account any strong positive or negative correlations that exist with the existing trades and only uses the AccountBalance() and NOT any draw down amount in equity.

	extern int maxPortfolioRisk = 30; // maximum amount at risk (0 = nothing; 100 = all)

	// this function returns the profit/loss if the stop is hit
	double profitAtStop( double open, double stop, double lots, bool isLong, string sym = "" ) {
	if ( sym == "" ) { sym = Symbol(); }
	double result = lots * MarketInfo( sym, MODE_TICKVALUE ) / MarketInfo( sym, MODE_TICKSIZE );
	if ( isLong ) {
	return( N( ( stop - open ) * result, 2 ) );
	} else {
	return( N( ( open - stop ) * result, 2 ) );
