My current code below is giving me Error 10. Array Subscript Out of Range

for( i = 0; i < BarCount; i++ )
{
	if( High[i] < High[i - 1] AND Low[i] > Low[i - 1] );
}

i+1 also is giving me same error.

Do not loop!

condition = H < Ref( H, -1 ) AND L > Ref( L, -1 );

where condition returns Boolean.

Thanks for the reply.

I need to find the high of the bar when the condition is met and using below code code to identify the price high. I am seeing a line only on the last high bar. I used watch to see the values in val , it is basically the High array.

_SECTION_BEGIN("Mini Coil");

val = Null;
P = Param( "Period", 3, 2, 10, 1 );
Cond1 = H < Ref( H, -1 ) AND L > Ref( L, -1 );
Val = ValueWhen(Cond1 = True, H);
PlotGrid(LastValue(Val), colorTurquoise, 1, 1);

_SECTION_END();

This = is ASSIGNMENT, not comparison. Comparison is ==. Please read the manual before anything else AFL Reference Manual

Also boolean value is already True or False. You don't need to compare boolean value to True to get True. Statements like if( Cond == True ) make no sense because it is essentially the same as saying if( Cond ) because that == True is redundant.
