I fear it was not or not completely. But the differences have been moved to PriceA/Asset_A compared to the previous version and sometimes the values are equal.

(Broker B has changed its minimum trade size to 0.1, so lot factor for Broker A is now 10)

Especially the last trade seemed very strange, Price_A had fallen from 14648 to 13914 within a second? So I asked ZHistoryEditor about Asset_A.t1 and found:

Code:
2018.01.02 18:00:09.000	13915
2018.01.02 18:00:01.000	13914
2018.01.02 18:00:00.000	13914
2018.01.02 17:59:58.000	13915
2018.01.02 17:59:57.000	13918

No idea where the value of 14648 came from. I compared randomly some further Price_A's from the log with the values of Asset_A.t1 and it was always like in the sample: the prices of Zorro's entries and exits are the ones that I also found in .t1. Anything seems sometimes to go wrong with setting PriceA = priceClose().
