Actually, I wrote a very simple EA just to see why I'm failing to open position on the renko chart only. 

So my EA includes only buy function and it fails (compilation is OK, but running it fails to open buy position). Can you send your email ? (mine is eyalgiga@gmail.com).

This my full simple EA just for testing the buy command (it works on regular chart, just not on renko).

Please Please Please fix my problem, Help !

#include <Trade\Trade.mqh>

CTrade trade;

int OnInit()

{ 

   EventSetTimer(1);

   return(INIT_SUCCEEDED);

}

void OnDeinit(const int reason)

{

   EventKillTimer();

}

void OnTick()

{  

}

void OnTimer()

{

   if (!TerminalInfoInteger(TERMINAL_TRADE_ALLOWED)) return;

   StartTrade();

}

void StartTrade()

{

   double Ask = NormalizeDouble(SymbolInfoDouble(_Symbol, SYMBOL_ASK), _Digits);

   if (PositionsTotal()==0)

   {

      trade.Buy(0.1, _Symbol, Ask, Ask-500*_Point, Ask+500*_Point, "buy");

      Print("Error while sending the order. Error# = ",GetLastError());

   }

}

I fixed the errors in your code.
You can change the symbol name from the inputs. 

#include <Trade\Trade.mqh>

CTrade trade;

input string Enter_Symbol_Name = "EURUSD";

int OnInit()
{ 
   EventSetTimer(1);
   return(INIT_SUCCEEDED);
}

void OnDeinit(const int reason)
{
   EventKillTimer();
}

void OnTick()
{  
}

void OnTimer()
{
   if (!TerminalInfoInteger(TERMINAL_TRADE_ALLOWED)) return;
   StartTrade();
}

void StartTrade()
{
   
   double Ask = NormalizeDouble(SymbolInfoDouble(Enter_Symbol_Name, SYMBOL_ASK), _Digits);
   
   if (PositionsTotal()==0)
   {
      bool send_order = trade.Buy(0.1, Enter_Symbol_Name, Ask, Ask-500*_Point, Ask+500*_Point, "buy"); 
      if(!send_order)Print("Error while sending the order. Error# = ",GetLastError());
   }
}

This is working !!!

You are THE KING !!

Thanks !!

Hello and Happy New Year for you, Family and friends.
I just have few questions/Comments pls:

1- For Live Trading: is KT Renko based on ticks or one minue data? 

2- For Backtesting: is KT Renko based on ticks or one minute data?

3- Whenever the terminal is restarted all the generated custom charts are re-generated again. For example if I have three Custom charts and I restrat the terminal, there will be new three custom charts inaddition the first three. Can you fix this please?

4-For backtesting, can you enbale (Full Reversal Bars)? 

Kind Regrads,

This is something I want to share for any trader who wants his EA to trade on Custom Charts in MT5.

Create an input string in your inputs. For ex: input string Trading_Pair = "EURUSD";

Click on (Control F)  inside your MQL5 code. This will open a Find Replace Window.

In the Find tab: Type Symbol().

In the Replace tab: Type the string input Trading_Pair.

Then click on Replace All

This should replace all Symbol() with the trading pair name.

Good day. In the tester, candles are drawn incorrectly (OHCL). And because of this, the advisor opens orders incorrectly.

Hi Andrei,

You're absolutely right to notice that, but this behavior is due to a known limitation of the Strategy Tester.

When a custom Renko chart is constructed in the tester, it's built using M1 data instead of actual ticks. As a result, the OHLC values may not be formed correctly, which can affect both the visual candles and order placement during backtests.

This issue is limited to the Strategy Tester environment. During live trading, the chart is constructed in real time using actual ticks, and the EA functions correctly without these inaccuracies.

Due to this limitation, the backtest results can sometimes appear overly optimistic. However, the purpose of backtesting on such charts is to get an approximation of the EA’s behavior and performance, which can then be used to make informed decisions in live trading, where no such limitation exists.

Thanks again for pointing it out!

Best regards,
Nitin

Hi, I just purchased this product. Wanted to generate Renko Chart for Symbol NAS100. I used NAS100 Chart and attached this Renko EA to generate Chart with input as 100. I could see that chart is generated for History data but it is not updating for live price values insead I get following message so I had to remove it from the chart. Here are the messages:

2025.07.17 18:24:26.468 Experts expert KT Renko Live Charts MT5 (NAS100,M1) removed

Hi Ashok,

Please try the following steps:

1. Close MT5, restart it and delete the old offline chart:

File → Open Offline → select NAS100_100_PIPS → Delete.

2. Open a normal NAS100 M1 chart, keep AutoTrading on and attach the EA again.

Are you sure about File → Open Offline  menu in MT5? I don't see this menu at all. Please sugest method to make it work.

I am sorry, I mixed the MT4 instructions with MT5. 
Could you please restart your MT5 and try creating a renko chart with 1000 pips instead of 100?
