NormalizeDouble Problem

Hi:

I have tried very much, but now totally dishearted!

I have this string str = "1.4060"

And i want to send an Order with this price.
I need to convert it in Double. So when i convert it to double using StrToDouble, it removes last 0 and return this 1.406

And OrderSend function is not accepting this value, it is return 129 error because amount of digits after decimal points are not normalized.

So i try it: NormalizeDouble(StrToDouble(str),4) But it is not working!

It should return 1.4060
But it is not adding last 0

Please help me, to make double 1.406 to 14060

Thanks
Burhan Khan

Your problem isn't with NormalizeDouble, look elsewhere.

Error 129 is invalid price, right? (I'd check, but on blackberry). I'm guessing that your submitting on the wrong side of market.

No! i triple checked it!

This is what MT4 saying in documentation:
Inserted Code
 If there has not been the requested open price in the price thread or it has  not been normalized according to the [url="help://predefined_variables_Digits"]amount of digits after decimal  point[/url], the [url="help://constants_errors"]error[/url] 129  (ERR_INVALID_PRICE) will be generated.


I have try it with manual input of 1.4030 and it is working fine.
But when i convert it from string to double then it is not working!

Any help will be highly appreciated.

If NormalizeDouble(StrToDouble(str),4) is returning 1.406, that IS 1.4060. That's why I'm saying the NormalizeDouble isn't your problem (provided you're trading on a pair that uses four decimal places, and I'm betting you're trading the euro).

Is there a reason you're specifying the value as a string in the first place?

Yes i am trading EURO.

Actually i am getting data from a file. And it is not CSV file, it is BIN file.

So i am getting all contents from file and store in a string variable. Then i am extracting PRICE value from it. It is ofcourse a string!

Ok i am agree that NormalizeDouble is not my problem. Then what is solution of my problem? How OrderSend will accept this value: 1.406 ?

Or how i add Missing Zeros in variable in order to accepted by OrderSend?
