Answers to questions

Where are you checking the Stops Level versus the current Ask/Bid prices?  I am not checking that , do i need to that because i am placing a TRADE_ACTION_PENDING order

Where are you aligning prices to the tick size?  I am not doing that, perhaps this is the issue?

What is the error code and trade result code?  code  4756

• Sell Limit Pending Order at 123.628 while Bid price is 132.629 (that is a 1 point difference). Even if Stops Level Freeze Level were to be 0 points (which might not be the case), the price to be filled can easily slip more than that and invalidade the order price, Do you really want to place a Pending order at 1 point difference? No, use a market order instead.
  
• Yes, you should always check the Freeze Level and Stops Level.
• Yes, you should always align prices with the tick size.
• Error code 4756 means "Trade request sending failed", but what is the trade result code?

You4 code should always check error codes and trade results codes and adjust to them.

You should learn to debug your own code and reference the documentation.

I have given you links, and suggestions. Now you need to do some research and put them into practice on your code.

Don't use pending orders so near to current market prices. Use Market orders instead.

NB! I did however make a mistake in my posts, You should in fact be checking the Freeze Level in respect to the open price of pending orders

The Stops Level is for checking against the Stop Prices, I have corrected my previous posts.

When you sell at market you use the current bid price not a different price.

   A sell limit must be above the market by at least MODE_STOPLEVEL * _Point or SymbolInfoInteger(SYMBOL_TRADE_STOPS_LEVEL).  Your sell price was below.

   There is no need to create pending orders in code.

   1. The pending has the slight advantage, A) you are closer to the top of the queue (filled quicker), B) there's no round trip network delay (filled quicker.)

      Don't worry about it unless you're scalping M1 or trading news.

   2. Humans can't watch the screen 24/=7, so they use pending orders; EAs can, so no need for pending orders, have it wait until the market reaches the trigger price and just open an order.
