MT5 - Bug in strategy tester? Creating trendline
further tests show, that the first point (leftTime, price) will be ignored by the strat tester. Now reported to the service desk.
Set anchor points separately and it will work.
Thx for your reply. As far as I understand anchor points and corners, they are not needed / valid for trend lines. Or am I wrong?

Dirk meant the trendline anchor points (time1,price1) and (time2,price2).
Thx for your reply. As far as I understand anchor points and corners, they are not needed / valid for trend lines. Or am I wrong?
I am sorry, I still don't get it...
How can I set the points (time1, price1) and (time2,price2) of a trendline other than I did?
if (!ObjectCreate(chart_id,name,OBJ_TREND,subWindow,time1,price,time2,price)) { Print("CreateTline---------- Failed to create a trend line! Error code = ", GetLastError()); return; }BTW, this is a copy from here and it works perfectly well outside the strategy tester

Please provide a code that compiles, so I can reproduce your issue.
Thx for your help... please find an example code from an indi below. It shows daily open lines on the chart
and is working well. Please attach it to a
profile and load the profile while testing a whatever expert in the
strategy tester. You will see what I meanPlease provide a code that compiles, so I can reproduce your issue.

Hi Alain,
any idea on the trendline problem?
BR
blackfriday
is there a way i could use any line atol in mt5 strategy tester? whether it be trendline, horizontal line, vertical line ?
@xxxxtttt777 #: is there a way i could use any line atol in mt5 strategy tester? whether it be trendline, horizontal line, vertical line ?
Your question is unclear. You can use all of those types of line objects in the tester, both on MT4 and MT5 Strategy Tester. So, please explain your question in more detail.

Hi,
I have coded an indicator, which creates trendlines (MT5). It is working without any problems with live ticks - but I am not able to get it working in strategy tester. Please have a look at the code below for creating the trendlines - with the test data, it should create a short horizontal line between two points. Pls find the result below the code
Result in strategy tester:
So the starting point of the line is correct, but not the end point. Again, the indicator is working flawlessly on live ticks, but I need the strategy tester for optimizing.
Any ideas would be appreciated...
Regards,
blackfriday
