I need to check if MACD value is negative or positive...  
iMACD(NULL, PERIOD_CURRENT, 12, 26, 9, PRICE_CLOSE, MODE_MAIN, i)

how do i do that? what function available or what custom code do you suggest?

Just need 'if' statement (reference):

double dValue = iMACD(NULL, PERIOD_CURRENT, 12, 26, 9, PRICE_CLOSE, MODE_MAIN, i);
if (dValue>0) { /* do something */ }
else if (dValue<0) { /* do other thing */ }

If the expression is true, operator1 is executed and control is given to the operator that follows operator2 (operator2 is not executed). If the expression is false, operator2 is executed.
