William, Not sure when the bar replay tool will be implemented in AmiBroker, but for the interim, the simulator tool is all we have. So if it is easy to fix current problem (if there is a problem) with simulator tool then that may be the way to go.
A little background on the problem I am having with the simulator tool. Before Amibroker I used to use Quotetracker. I had a lot of historical intraday data that I collected using Quotetracker. Here is an example of the data from Quotetracker: 02/23/05 9:49:30 4122 02/23/05 9:50:00 4121 02/23/05 9:50:01 4121 02/23/05 9:50:01 4121 02/23/05 9:50:04 4121 02/23/05 9:50:04 4120 02/23/05 9:50:05 4121 02/23/05 9:50:08 4121 02/23/05 9:50:10 4121 02/23/05 9:50:11 4120 As you can see it's essentially tick data. I imported all my intraday data that I collected from Quotetracker into Amibroker. I am using the standard version of AmiBroker. When it arrives in AB, the data is "massaged" during the import so that it appears in AB in 5 second chunks. The reason for this as outlined by Tomasz is: "This is due to the fact that AmiBroker uses its own 32-bit datestamp that has resolution of 5 seconds". The problem I am having with simulator tool is with these data files that I imported from Quotetracker. With these data files, the resulting chart from the simulator is different to the original. It may have always been this way, but from memory I thought I ran the simulator on a lot of this data over a few months without any problems. As I said before, I have used the simulator quite a lot and I don't ever remember having a problem, and I can't imagine that I never ran it against any of these data files. This led me to believe that the behaviour of the simulator tool had changed recently. The simulator tool also runs much slower on these data files then it does on data that has been collected using the IB plugin. The data I collect via the IB plugin is in 1 minute chunks, the smallest Base Time Interval possible with the AB standard version. And the simulator runs fine against this data, resulting chart is exactly the same as original, and it runs much faster against this data too. So the simulator tool appears to have problems with imported data that is in tick format, at least that appears to be the case with the standard version of AB, I can't comment on the professional version. I will send you some data files if you think this is worth pursuing further, or you could simply import some tick data into the standard version of AB and probably duplicate the problem yourself. I can work around the issue, just means I can't do any testing with the simulator on data that I imported from Quotetracker (or any other tick data I import). I think the simulator is a valuable tool, and if this problem is easy to fix then that may be worth doing, particularly as there is no time frame for the replay tool built into AB.

Subject: [amibroker] Re: Is Simulator tool broken? Hi Thomas, I have found a solution to that problem and made some modifications to the simulator tool which seems to work well but I have some better news for you. Tomasz has indicated that a bar-replay tool will be incorportated in with AmiBroker however I am not sure of timeframe for release. At this stage I will not do any more work on that simulator program because you will get something much better from AmiBroker.
