Okay thanks, but see the message I posted 1 minute before yours.

I found something.

_Point and MarketInfo(_Symbol,MODE_POINT) are both = 1e-05 !?

In MQL programming, _Point is the smallest unit of price change, for example, price in EURUSD change every 0.00001, while price in GBPJPY change every 0.001.

MarketInfo(_Symbol,MODE_POINT):

Point size in the quote currency. For the current symbol, it is stored in the predefined variable Point

So yes, just two different ways to get the same value.

What? You didn't explain why I get the useless value 1e-05 instead of 0.00001 or 0.001.

This is the so called exponential or E notation.

https://en.m.wikipedia.org/wiki/Scientific_notation

1E-5 equals 1 x 10‐⁵ = 0.00001

1E5 or 1E+5 equals 1 x 10⁵ = 100.000

Do yourself a favor and read the damn wikipedia link.

Wow, okay. I give up. Reread everything I wrote from the beginning. All your questions are long answered.

Why don't I get the numerical notation like I'm supposed to?  Knowing that it's the same thing doesn't explain why it breaks my code.

Sorry. Looks like there was no supernatural explanation this time. I had just forgotten to comment out a faulty function that I had just modified, or something like that. At least I learned something about the scientific notation.

Still a question remains: why did the search results disappear? Yesterday I said: " I just noticed that the results I was getting earlier when searching for 'e-05' on this forum have disappeared. "

Are you stupid or just kidding us ? 

Ask-Bid = <spread>e^05 ; it won't change your ea's math.

If you need to display it fully as a text then : 

printf("%s",DoubleToString(value,8));

Got it ?

I just said the problem was not in the scientific notation, so there's no need to talk about that anymore.
