If I used the first function, normally the values with "-1.49" and "-0.12" are not in the area of trues!!

(the written of the textfile: with "##_" is false, and without is true)

I get this in my Textfile...

sometimes I get a true-value, and sometimes a false-value.

Thats a problem if I work with money!! :-(

You can search by: "strg+F" with the value "-0.12"!! CRAZY...

PS: MT4+ Values: 2011.11.01 - 2011.12.01, EUR-USD, M1, only OpenPrice, Spread2

When posting code . . . please use the SRC button to post code: How to use the SRC button.


Not crazy, it's the way in which double values are stored in memory . . .

-0.12 can != -0.12 read this thread: Can price != price ?
