That they can't reproduce the error.

You should not comment on NinjaTrader, as it is not very objective. I suggested to use add MaximumBarsLookBack = MaximumBarsLookBack.Inifinite for all their indicators with recursive formulae and they responded that they forwarded the suggestion to development.

The customer service of NinjaTrader is quite good. They have repeatedly logged into my PC to check errors they could not reproduce. But most of the errors, let us say 95% (using percent is quite appropriate, as the denominator is 100) could be reproduced sooner or later and has been settled in one way or another. The problem is that there are still lots of new bugs being detected.

All these little things are just annoying. It shows a lack of experience/knowledge, as shows the painful progress towards the final release of NT 7. They simply have underestimated the task of putting up a software, which is as feature-rich as NinjaTrader.

NinjaTrader (chart trader) today duplicated some of the trades on the sim account, while I did them only in the real account. P/L is splitted between sim and real account. When a sim trade closed, P/L of both real and sim were updated. During trades I heard "Stop filled" and "Target filled" several times, while having no open positions... that was a little scaring.

This is obviusly a bug. I didn't change the account in chart trader. The sim trades were by no chance made by me, it was like a hidden strategy was running on the sim account. I don't even ever touched anything about "strategies" on this production machine, which is a brend-new dell with plenty of ram and only ninja trader installed.

See screenshot. The sim trades were done automagically by ninja.

Some time ago I reported a similar bug to ninja support. They replied that was my fault, because, they said, I pushed the "REV" button on chart trader. I didn't pushed that button, but I was not 100% sure so I gave up. Now I'm 100% sure I didn't selected the sim account, I was live trading.

I believe it is not just an underestimate because, in software developing, every project is always underestimated ;-)

I believe they simply lack a professional software methodology in place. They can have great programmers, but in today complex software projects a modern methodology in place is necessary. Having worked many years as a software developer, I can smell how ninja started a little amateurish style years ago, and never really changed this approach. I remember they even stated something like this in their forum.

They clearly don't adopt a test-driven approach, otherwise all this new and repeating bugs didn't were here.

Let me say that a bug like this, is not a bug, is bad design. A well designed software, with proper code encapsulation, class hierarchy with self error testing, should not expose a bug like this. I think the code is a bit messed-up spaghetti-like. In fact, I would design polymorphic classes well isolated in terms of active strategies or account. Of course I can't prove it, but these are the types of error you usually find in software where object oriented design is mixed with procedural style coding. I know because I have made this errors myself, in the beginning.

So now I think ninja will never act as advertised, because of bad designed code. Too bad I purchased a lifetime license.

I also own a lifetime license. I also think that it never will be care-free. But I can use it for discretionary trading with some precautions. It has an excellent look and feel, usability is perfect. I would never trust in such a tool to do automated trading or backtesting.

The time I have invested is not wasted. I can reuse my knowledge for other platforms. The amount I have paid for the lifetime license is sort of a tuition fee.

Why do you think @Zondor and I started several threads about optimizing NinjaTrader code? When @Richard Todd, from move the markets got involved I was supremely satisfied with the results.

Much of the work Zondor and I did was to make NT7 stable. It is for us. I routinely execute live, real $$$ trades. Most if not all of the problems are my fault. Today was a great example of being able to execute a live trade any time I wanted from any one of 3 different live accounts.

Yes, if I had to eat it.

I'm glad NT is working well for you.
I can accept if NT crashes because of code written by me, but my only fault was using the chart trader. I believed I could trust chart trader, it is not its first version, it should be a mature component, but it is not.
During this month I had a position reversed by NT, and the support guys convinced me that I clicked the REV button, while I didn't. Today some sim trades apperead by themselves while I was trading.

I appreciate NT is trying to show me how to trade, this must be an undocumented feature, the next step in autotrading.

I will be making videos of my trades for a few days, just so I have a record of exactly what happens. Someone posted how to obscure my account, but as usual, I can't find it. Will look for it later. Any hints are appreciated, as I know it is on the Web, somewhere... as well as on the Price, Volume & the DOM thread.
