How to start with MQL5 - page 40

DroidM #: I can't figure out what I'm doing wrong, but it doesn't return true.

1.    CopyRates(_Symbol,_Period,0,Candles,rates);
   

   You read [0 … Candles-1] values into rates.
   

2.    for(int i=5; i<Candles; i++)
   

   Variable i goes up to Candles -1.
   

3.    for(int l=i; l<i+candles; l++)
   

   Therefor, variable l goes to Candles-1+Candles-1.
   

4.       if(rates[l+1].close>rates[l+1].open && rates[l+1].low>rates[l+2].low)

   Therefor, l+2 reaches [Candles … Candles-1+Candles-1+2]. Array exceeded. Crash.

Creating a ticker tape panel: Basic version

Some people may find price tape panels that are built into some platforms and that display individual asset quotes pretty cool.
This idea is quite interesting to implement and develop and it can also be a very useful resource for many, which is why I decided to show how to create the code for such a panel.

Creating a ticker tape panel: Improved version

In the previous article Creating a ticker panel: Basic version, we have seen how to create an indicator in the form of a panel displaying a tape of real-time symbol prices. However, in the previous article we did not implement the indicator completely, not because it was impossible, but because our goal was to show the process of creating the indicator, to see how to make it work with the least amount of code in order to give the impression that it moves.
But this data is not always enough and does not always reflect what people really want to see on the panel. It would be great to have some more details. This is what we are going to implement here.

PositionGetInteger(POSITION_TYPE) problem

Hi, I'm trying to use if(PositionGetInteger(POSITION_TYPE) == POSITION_TYPE_SELL) to work on the sell order but i found out that it doesn't work because it always return POSITION_TYPE_BUY no matter the order is sell or buy........ really don't understand what's happened or is there any bug anyone encountered?

Here are my sample code and the print out log showing both sell and buy order return  POSITION_TYPE_BUY. Thanks a lot if anyone could help. Thanks.

void OnTick(){

   if(PositionsTotal()==0){
      trade.Buy(0.01);
      Print("Pos type is ", EnumToString((ENUM_POSITION_TYPE)PositionGetInteger(POSITION_TYPE)));
      trade.Sell(0.02);
      Print("Pos type is ", EnumToString((ENUM_POSITION_TYPE)PositionGetInteger(POSITION_TYPE)));
   }
}

It doesn't return POSITION_TYPE_BUY each time, it returns 0.

What are trying to do will never work, because you sent a trade request on the server, that doesn't mean you already have a position. It needs some time to be executed and the Terminal notified about it.

Calculate Positions and Pending Orders

Code:  Calculate Positions and Pending Orders.mq5

Open positions: GBPUSD BUY 0.03 lot and USDPLN SELL 0.01

Pending orders are placed: USDPLN Sell limit 0.01 and GBPUSD Buy limit 0.03

Hi @Vladimir Karputov, thank you so much, this thread is priceless, so many useful snippets. Please, I went though all pages but I didn't find how to calculate the average price of a set of orders (hedge accounts), probably using the History, lets say that I bought 1 lot at 5.00, 2 lots at 5.5 and sold 0.5 lots at 5.80, then I would expect 3 lots averaging (1*5 + 2*5.5)/3 of average buy price and 0.5 lot averaging 5.80 for sell price, would you have such snippet around? thanks!

You can try to find it by yourself - read this thread about HowTo:

How can I search for indicators and other elements in this forum?

Everything you need to learn about the MQL5 program structure

Every software in any programming language has a structure, after understanding this structure we can create or develop our software smoothly. MQL5 language's programs are the same as any other programming language has their structure and it is supposed to be understood by the developer to achieve the objectives of his project smoothly and effectively. In this article, we will provide information in this context to try to deliver its content easily as possible.
