for (int i=0; i<=OrdersTotal(); i++) { if(OrderSelect(i-0,SELECT_BY_POS)==true) int type = OrderType(); bool result = false; ⋮
Your if statement does nothing. You continue even if the select fails. I prefer:
for (int i=OrdersTotal - 1; i > 0; --i) if( OrderSelect(i,SELECT_BY_POS) && OrderMagicNumber()==MagicNumber ){ int type = OrderType();

You should be able to read your code out loud and have it make sense. You would never write if( (2+2 == 4) == true) would you? if(2+2 == 4) is sufficient. So don't write if(bool == true), just use if(bool) or if(!bool). Code becomes self documenting when you use meaningful variable names, like bool isLongEnabled where as Long_Entry sounds like a trigger price or a ticket number and “if long entry” is an incomplete sentence.

In the presence of multiple orders (one EA multiple charts, multiple EAs, manual trading), while you are waiting for the current operation (closing, deleting, modifying) to complete, any number of other operations on other orders could have concurrently happened and changed the position indexing and order count:

For non-FIFO (non-US brokers), (or the EA only opens one order per symbol), you can simply count down, in an index loop, and you won't miss orders. Get in the habit of always counting down.
Loops and Closing or Deleting Orders - MQL4 programming forum -
For In First Out (FIFO rules — US brokers), and you (potentially) process multiple orders per symbol, you must find the earliest order (count up), close it, and on a successful operation, reprocess all positions (from zero).

and check OrderSelect in case later positions were deleted.

and if you (potentially) process multiple orders, must call RefreshRates() after server calls if you want to use, on the next order / server call, the Predefined Variables (Bid/Ask.) Or instead, be direction independent and just use OrderClosePrice().

please suggest if logic is correct or not.
