Doubles are rarely equal. Understand the links in:

You buy at the Ask and sell at the Bid. Pending Buy Stop orders become market orders when hit and open at the Ask.
-
Your buy order's TP/SL (or Sell Stop's/Sell Limit's entry) are triggered when the Bid / OrderClosePrice reaches it. Using Ask±n, makes your SL shorter and your TP longer, by the spread. Don't you want the specified amount used in either direction?
-
Your sell order's TP/SL (or Buy Stop's/Buy Limit's entry) will be triggered when the Ask / OrderClosePrice reaches it. To trigger close to a specific Bid price, add the average spread.

The charts show Bid prices only. Turn on the Ask line to see how big the spread is (Tools → Options (control+O) → charts → Show ask line.)
Most brokers with variable spreads widen considerably at end of day (5 PM ET) ± 30 minutes. My GBPJPY (OANDA) shows average spread = 26 points, but average maximum spread = 134 (your broker will be similar).

- Lot Size must be a multiple of Lot Step and be at least Min Lot.

Thank you for your reply, but I don't quite understand your answers... What exactly do I have to change for my program to work? I think it's in the Ask, because in the other programs the change of order works without any problem...
Thank you in advance.
Everything! You have to change everything, because it is ALL wrong!
Try to first learn the language properly, before attempting to write an EA.
You will also have to learn the trading concepts as well, not just the coding. Without the trading knowledge you will not know what to program.
For the coding, I suggest reading a book, for example this one:

Please edit your post and use the code button (Alt+S) when pasting code.
EDIT your original post, please do not just post the code correctly in a new post.
priceinit = Ask; if (Ask==priceinit+100*_Point && OrdersTotal()==0)
This is the same as
if (Ask==Ask+100*_Point && OrdersTotal()==0)
Do you really think that Ask can equal Ask + n ??

Yes thank you, it seems to be a very good book, do you think it is complete and covers all the concepts of programming in MQL4?
Thanks

1) Yes, I see... Usually it was done automatically without me having to do any manipulation...
2) Yes, that's exactly what I was thinking, but how do you lock in the price of priceinit at ASK? And that as soon as the ace has taken 10 points from Price init then place a buy order? The worry is to lock in the value of the price init? But how to do it?
Thanks a lot
