[amibroker] Multi Time Frame Indicator example

[G_R_O_W_L_Y]

Hello

I had a go at trying to modify one of Tomasz Janeczko's sample multi 
time frame scaning formulas. All i get showing up is MTRSI = {empty}. 
Any ideas as to why this is would be greatly appreciated?




Count = 0; 
result = 0; 
final = 0;

for( i = 5; i <= 360; i = i + 5 ) 
{ 
   TimeFrameSet( i * in1Minute ); 
   m = RSI(); 
   TimeFrameRestore(); 
    
   m = TimeFrameExpand( m, i * in1Minute ); 
    
   result = result + IIf( m > 70, 1, IIf( m < 30, -1, 0 ) ); 
   Count++; 
} 

final = result / Count;
plot( final, "MTRSI", colorBlue, styleThick );
plot( EMA(final, 7), "EMA(MTRSI,7)", colorLightGrey);
