Title: Simple code problem

Rush,   these type of calculations can be done using arrays only, like   Periods = Param("Periods", 5, 2, 200, 1, 1 ); mo = MA( Open, Periods); mh = MA( High, Periods);   mc = MA( Close, Periods); TheDiff = IIf(mo < mc,mh - mc,IIf(mo > mc,mh - mo, 0)); Color = IIf(mo < mc,colorBlue,IIf(mo > mc,colorRed, colorGreen)); Plot( TheDiff, "SC Plus", Color, styleHistogram);       You can also do it using loops. However you can take              mo = MA( Open, Periods);            mh = MA( High, Periods);             mc = MA( Close, Periods);   outside of the loop like (then it goes much faster):   Periods = Param("Periods", 5, 2, 200, 1, 1 );        Color = Null;      TheDiff = Null;        mo = MA( Open, Periods);      mh = MA( High, Periods);       mc = MA( Close, Periods);         for( i = 0; i < BarCount; i++ ) {             if(mo[i] < mc[i]){                 TheDiff[i] = mh[i] - mc[i];                 Color[i] = colorBlue;            }else if(mo[i] > mc[i]){                 TheDiff[i] = mh[i] - mo[i];                 Color[i] = colorRed;            }else{                 TheDiff[i] = 0;                 Color[i] = colorGreen;            }        }   Plot( TheDiff, "SC Plus", Color, styleHistogram);           ----- Original Message ----- From: Rush To: amibroker@yahoogroups.com Sent: Saturday, April 01, 2006 12:59 PM Subject: [amibroker] Still confused Hi,   I’m still confused on how to use the variables.  The code below seems to work but slows AmiBroker down.  It seems that the “if” statement doesn’t like to see the variables mo, mh, mc without the square brackets.  All I’m trying to do here is plot the difference between the average high and average open/close in a colour depending of the result as a histogram.   Question: is it possible to define a variable that is not an array?   Periods = Param("Periods", 5, 2, 200, 1, 1 );        Color = Null;      TheDiff = Null;        for( i = 0; i < BarCount; i++ ) {              mo = MA( Open, Periods);            mh = MA( High, Periods);             mc = MA( Close, Periods);             if(mo[i] < mc[i]){                 TheDiff[i] = mh[i] - mc[i];                 Color[i] = colorBlue;            }else if(mo[i] > mc[i]){                 TheDiff[i] = mh[i] - mo[i];                 Color[i] = colorRed;            }else{                 TheDiff[i] = 0;                 Color[i] = colorGreen;            }        }   Plot( TheDiff, "SC Plus", Color, styleHistogram);     Please note that this group is for discussion between users only.
