Incorrect TP value

Davi Santos Da Silva 2019.07.31 01:13

Hello Developers,

I need your help to solve a peculiar case.

My problem happens when sending TP and SL for orders.

EA seeks TP of only 10 points. However when opening orders this distance is not being respected. For example, if I open a buy order by placing a 10-point TP, there are times when the order closes at 0 profit or sometimes even in lose trade.

I am using for BUY orders the sum of TP along with Ask price and SELL orders with Bid price

I don't know if I'm handling orders in the right way. Can anyone please analyze my code and help me solve this problem?

In the following image the EA had a TP of 10 points or 1 pip, in the first order respect the values, but in the second order opened with the same entry price.

I also attached the original EA

Thank you

Your stops have StopLoss/Takeprofit Points minus spread for buys and that plus spread for sells.) Don't you want the same amount for either direction?

You buy at the Ask and sell at the Bid. So for buy orders you pay the spread on open. For sell orders you pay the spread on close.

Your buy order's TP/SL (or Sell Stop's/Sell Limit's entry) are triggered when the Bid reaches it. Not the Ask. Your SL is shorter by the spread and your TP is longer.
Your sell order's TP/SL (or Buy Stop's/Buy Limit's entry) will be triggered when the Ask reaches it. To trigger at 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.)

How can I intergrate how to code this Calculate TP for ECN

Brian Rumbles 2019.07.31 01:49 #2

Hi, I have looked at your code. I will tell you my understanding, so I apologize in advance if it does not help.

The code executes the 1st trade differently to the subsequent trades. This is what the function openfirsttrade() is for.

However, in your Buy function and sell function, The code refers to sl!=0 AND tp!=0, but I cannot see in your code any defined values for tp and sl.

in the line where they are declared they are not assigned any value.

So I would recommend to assign a value to sl and tp and try run the code again.

Hello William Roeder

Thanks for taking the time to help me.

Can you please enlighten me a little more?

As in the example above I used Bid price to Sell and Ask price to Buy with the TP and SL. This way I thought I already added the spread because I was using the opening price as a reference for my TP, and after that i only needed to add the distance of the TP.

For me to at least guarantee that my order will have the value of TP plus spread, what is the correct way?

Thanks in advance

I used this video as a reference

incorporate spread in calculating Calculate TP for ECN Stoploss points are higher

Hello, thanks for the help, but in the code above I put TP and SL as input for users
