Wow, that's quite a journey you've been on, Nuno! I admire your persistency, many would have quit long time ago. Thumb up.

Thanks footon
I would say: this thing was starting to put my trust into question, so I made an effort because I like the program a lot. The balance was very positive for everyone as well, because an important bug was found out.

After having increased the max number of intrabars, the problem maintains. For the same strategy, I get:

- lots of ambiguous bars with a large file with 1min data since 2000 (even if data horizon starts in 2013). This file and the strategy can be downloaded here: https://www.wetransfer.com/downloads/70 … 018/c93338;
- only one ambiguous bar with the small file with 1min data since 2013. This small file was obtained from the large one. I've sent in a previous post these data.

When I use the large file, FSB Pro tells me that around 50000 1min bars were loaded (I have more than 1 million).

I am only using 1min and 1440min data now, not the other timeframes.

What is happening here? Now I'm lost!!

I attach the bar explorer of both backtests (see two tabs).

Thanks again
Nuno

Change values of the following settings:
"MaximumBarsLimit": 50000,
"MaxIntrabarBarsLimit": 100000,

For me it works fine.

Please check if there is no broken or missing data for 31.12.2013 for other time frame - 4H, 1H... or for fast test remove all intermediate data files

I think you are right, it had to do with the date. Thanks to that I've just discovered that MT4 places all history in a new folder...

I've found however another ambiguous bar with the same problem. I'll do the same thing, but I wonder if that fact that only 100000 intrabars are allowed could also explain the issue?

I confirm, it seems to be related to the number of intrabars allowed. I have data since 2000 for SP500, so I would need this number to be increased?

For me it works fine.

It's not clear in this screenshots for what bar you speak. What is the strategy time frame?

Please post full data info (Time OHLC)  for bar No 223 for the strategy time frame.
Post 1min data (Time OHLC) for the time span of bar 223

Sorry I'll explain better. The MT4 screenshot is 1 min data for 31/12/2013. It corresponds to intraday data for bar 223, which is a 1 day bar (the strategy runs on daily data). Do you still need the original data?

Please post full data info (Time OHLC)  for bar No 223 for the strategy time frame.
Post 1min data (Time OHLC) for the time span of bar 223

- I have 1 min data in FSB (and the same data in MT4)
- Long position opens at 1841,3
- BE is set to 1841,3 when the price reaches 1843,8 (BE=25 points)
- As you can see through the real 1 min data bars, the price never reaches again 1841,3, so the BE is in reality never activated

In fact, the bar should not be considered ambiguous. It is not ambiguous. If the program is able to check 1 min data, the price action leaves no room for doubts, and the position would be closed with a profit.
