[BUG] AllTrades in Markert Replay

[12tkram]

Hey, of course, they are not the same script, I know this, I copied in the OnPositionUpdate() function from your script into my script ..,

The offending line is the following from your OnPositionUpdate() function ..

 Print(string.Format("{0}", SystemPerformance.AllTrades[i].ToString()));

from the loop

if (SystemPerformance.AllTrades.TradesCount > 0)                 {
                    Print(string.Format("{0} AllTrades.TradesCount: {1}", Time[0], SystemPerformance.AllTrades.TradesCount.ToString()));

                    for (int i = 0; i < SystemPerformance.AllTrades.TradesCount; i++)
                    {
                        //Print(string.Format("{0}", SystemPerformance.AllTrades[i].ToString()));
                    }
                }

I can't print the values of that line because of the error below.

--
Strategy '<name>197047982': Error on calling 'OnPositionUpdate' method on bar 15310: You are accessing an index with a value that is invalid since it is out-of-range. I.E. accessing a series [barsAgo] with a value of 5 when there are only 4 bars on the chart.

If I comment out that offending line, or remove your OnPositionUpdate() function my strategy script works fine.

All I wanted was to write some values from each of the trades as they happen/exit into a file, I found your code when looking how to access trade info, so I thought looping through the trade list and printing the data was the first step, but I have not made it past that bit yet :?

I hope that clarifies the sequence of events .. I am in no way saying that our 2 x scripts are the same, they are not, but the OnPositionUpdate() is the same in both.

There is something going on in my script that is stopping me looping through the list of trades and extracting the data, which, I have no idea where to go with that .. should just work right ? am assuming you have not seen this before and its not a bug/defect ?

Is there some sort of low level debugger we can attach or run ?

Hello 12tkram,

What is the value of i when the error occurs?

What is the value of SystemPerformance.AllTrades.TradesCount?

Below is a link to the help guide on VisualStudio debugging. This would start falling outside of what I may assist with and why our support relies on prints.

Hello 12tkram,

The index appears valid. My suspicion is you are looking at the wrong index.

A suggestion would be, you could use the script I have provided you as a starting strategy and then add your code to it since we know this is working.

K, yeh, add sections at a time, sounds like a plan.

done and it works, the only thing I found to cause a bars error was as erroneous "IncludeTradeHistoryInBacktest = false;" in (State == State.Configure) .. however, commenting that out of the original did not fix the issue .. not even sure what fixed it, all sections pasted in fine, tested after each paste until the complete code was copied over .. thanks for your help again .. expect there is some weird character somewhere in the orig ..
