Loosing data on Strategy Analyzer log entries.

[d3whiteley]

I'm trying to run my strategy through the Strategy Analyzer. I want to be able to compare prior runs, but in the log, the results seem to get corrupted. As soon as I run the strategy again, the # of trades and Total net profit go to zero. If I run the same setup twice and go back to the prior run, it looks totally different. Is it time to re-install NT8? I've tried deleting the cache, tick, day, and minute folders and that doesn't seem to help. I've tried with and without tick replay and different timeframes. Same result.

Hello d3whiteley,

Are you able to reproduce this with the SampleMACrossover included with NinjaTrader?

Are you connected to a data feed when re-running the test?

[d3whiteley]

Yes, I am connected to my usual data feed while running. I also ran the Sampe MA Crossover, and it works ok, so it is something in my strategy code. I did some testing. I was wondering if it may be my using the Draw functions for ArrowUp, ArrowDown, and DrawText so I removed that code, and it started working. Put it back in and started removing smaller pieces to track it down and ended up with it all removed again but still not working.

Hello d3whiteley,

In general we recommend avoiding drawing objects when backtesting by checking IsInStrategyAnalyzer.

If you comment out all logic, variables, and properties, then copy the simple crossover logic and retest and try the log are you still able to reproduce?
