hi, you have the same variable name for your result and you deviation of the envelopes.
double BotBand1 = NormalizeDouble(iEnvelopes(NULL,0,FastMAPeriod,MODE_SMA,0,PRICE_MEDIAN,BotBand1,MODE_LOWER,1),5);
double TopBand1 = NormalizeDouble(iEnvelopes(NULL,0,FastMAPeriod,MODE_SMA,0,PRICE_MEDIAN,TopBand1,MODE_UPPER,1),5);
double TopBand2 = NormalizeDouble(iEnvelopes(NULL,0,FastMAPeriod,MODE_SMA,0,PRICE_MEDIAN,TopBand2,MODE_UPPER,1),5);
double BotBand2 = NormalizeDouble(iEnvelopes(NULL,0,FastMAPeriod,MODE_SMA,0,PRICE_MEDIAN,BotBand2,MODE_LOWER,1),5);
.
.
.use other names for setting the deviation and your code looks good. i am surprised that it will compile without errors, but thats mql4.
Sorry, That was a typo. I didn't copy and paste that code from my ea. It was supposed to be this;
double BotBand1 = NormalizeDouble(iEnvelopes(NULL,0,FastMAPeriod,MODE_SMA,0,PRICE_MEDIAN,Bot1,MODE_LOWER,1),5);
double TopBand1 = NormalizeDouble(iEnvelopes(NULL,0,FastMAPeriod,MODE_SMA,0,PRICE_MEDIAN,Top1,MODE_UPPER,1),5);
double TopBand2 = NormalizeDouble(iEnvelopes(NULL,0,FastMAPeriod,MODE_SMA,0,PRICE_MEDIAN,Top2,MODE_UPPER,1),5);
double BotBand2 = NormalizeDouble(iEnvelopes(NULL,0,FastMAPeriod,MODE_SMA,0,PRICE_MEDIAN,Bot2,MODE_LOWER,1),5);
I am still only seeing one set of upper and one set of lower bands in the chart window. (When I click 'Open chart' in the tester).
Any ideas on how to create these bands with point deviation instead of percent???
Do I need to create my own custom function using buffer arrays around an MA ? Any advice?
Many thanks,
Chris.

Hi,
Could anyone please help me to understand the use of buffers. I need to create two upper bands and two lower bands around a simple MA. I used ienvelopes, but the deviation is in percent. I need to use a point value.
Here is a sample;
double BotBand1 = NormalizeDouble(iEnvelopes(NULL,0,FastMAPeriod,MODE_SMA,0,PRICE_MEDIAN,BotBand1,MODE_LOWER,1),5);
double TopBand1 = NormalizeDouble(iEnvelopes(NULL,0,FastMAPeriod,MODE_SMA,0,PRICE_MEDIAN,TopBand1,MODE_UPPER,1),5);
double TopBand2 = NormalizeDouble(iEnvelopes(NULL,0,FastMAPeriod,MODE_SMA,0,PRICE_MEDIAN,TopBand2,MODE_UPPER,1),5);
double BotBand2 = NormalizeDouble(iEnvelopes(NULL,0,FastMAPeriod,MODE_SMA,0,PRICE_MEDIAN,BotBand2,MODE_LOWER,1),5);
When I backtest my system, and open chart window, Only one set of bands are visible.
Is there a way of creating a similar set of bands using buffers[]. Does anyone have a relevant code sample for use in ea.
Many thanks for any help.
Chris.
