MT4 Tester errors

New comment
 
I realize that all testing with the strategy tester is purely simulated from the data supplied. In testing an ea that I developed I noticed that particularly with the short trades the tester would take trades outside of the range of the candle for that period. This results in some huge errors being made.

I think it must be something wrong with the way the tester handles the data whereever it is from.

Did You consider that charts are built on bid prices only?

Yes I did consider that but the trades are still significantly outside of even that range
 
In the visual mode too?

I have see this poblem too : in visual mode, sometime a bar is drawn but the price (bid) doesn't reach the high or low of that bar.
 
Yes it is interesting because it doesn't happen all the time. It will run for a while then it reaches a point then it takes a bunch of trades well outside of the candle. Then continue merryly along its way only to do it again a little while later. I tried looking for a relationship in the times from ech other but don't have the skill to be accurate enough.

Print ask and bid every tick and analyze their value
