55.93 under testing. Has a few bug fixes and data folder trees are shrunk bu default. I may not release till more significant improvements made.
Current build 55.90 seems quite good.
Support ticket placed to MC about their bugs that cause mc <> gsb was done today. 
The ticket was
"We have recently discovered two serious bugs in indicators calculation that return incorrect values for many, and sometimes all, bars.
The first issue appears whenever we call an indicator of another (for example, HighestFc(AverageFC)) of a secondary data (such as Data2, Data3, etc.).
This issue is mainly related to filtered data (or in other words, missing bars in the secondary data), which is quite common.
Moreover, the second issue is that the vars-call (as in value1=AverageFc; value2 = HighestFc(Value1) gives different values compared to inline-calls (as in HighestFC(AverageFC)) , which is very confusing. After multiple tests, we have found that the vars-call is specifically wrong for some bars
after Data2 date-gap (missing-bar compared to Data1), but the inline-call is nearly wrong in most bars, and even in Data1, unfortunately.
In the attached workspace, we have used a test data (CL as Data1 and HO as Data2) and a small indicator (MC_Test_Data2) to plot both var-call and
inline-call and log them to files for an easy compare. " |
