Problems with V7.9: different efs results

[dungn6au47]

Dear all,

My efs files (few thousand lines of code) developed using eSignal V7.6, now give very different results when tested with V7.9 (not tested with V7.7 & 7.8 yet). Anyone has had similar problems or has any suggestions how to locate the causes/to fix the problem

Hello Dung,

Please post your code as an attachment so we can take a look. Also, please post some chart images or more detailed information about the differences you're seeing.

There were some incompatibilities in 7.9 that are hopefully resolved in the upcoming 7.9.1 beta (should be posted today, join the '7 Series Beta' fileshare group to receive notification of that).

Hi Jason & Dion

Thanks for your replies.

Attached is a screen shot of my efs running with V7.6 the end result (at the right top corner) is 12.59% ($4.88) profit.

The next screen shot running with V7.9. the end result is 1.65% ($0.61) loss.

The 2 charts show clearly that trades are executed at different locations.

I debugprinted various variables at end of each bar. One point that catch my attention is the difference in volume values [V = vol()]. V7.9 gives V exactly 40000 for every bar, while V> 40000 (eg 42500, 47600, ...), rarely equal to 40000 with V7.6 . Note that interval used was 40000V. I think this is a cause of different results by the two versions. V7.9 uses interval mathematically exact to 40000, but this is rarely happenning in real trading. Why change the method of determining interval ? What is the convention ?
