MC 5 optimizer doesn't seem to free up memory for trend line

Hi, I just started to upgrade my strategies from MC 2.1 to 5.0 and got into the following issue: During optimizing one strategy the memory for MC 5 just went up to +/- 2Gb and then MC crashed. Because this didn't happen in MC 2.1 I tried to figure out why. It seems that the 5 optimizer doesn't free ...

Hi Marina,

Thanks! As you know, I will stay for the time being on release 2.1. It's the best one for me right now.

When the new version is out I will test it.

Hi Marina,

Thanks for your answer. Do I get an update/patch? I don't want to go to a beta version (5.x) to solve this problem because a beta is to risky for me to run in production.

Thanks again,

Maximum number of shares/contracts per position

Hi Marina, It's a long time ago I had support from you; the last half year I'm running several MC (2.1.999) instances on DEV, TEST and PROD without serious problems. Great! Because I had to upgrade my Java (1.6.0_10) and TWS (888.3), the IB datafeed from MC 2.1 was not stable anymore. That's the rea...

Wrong behaviour Mod() in combination with TimeToMinutes()

Hai Marina, I ran into a strange behaviour of MC (2.1 and 3.0). The result of the expression: Mod(TimeToMinutes(time) - TimeToMinutes(0900.00), BarInterval of data2) = 0 returns (only) at a 16.20u bar false instead of true! I can show it via Live Helpdesk but it's also easy to reproduce. Can you giv...

Not all contracts are closed when marketposition reverse

Marina, It looks like that not all open contracts are automatically closed by MC when the marketposition reverses. Contracts are left open until the end of the chart. This gives unexpected results. It only happens when the # contracts in the second order > 1. Please comment on this. Thanks, Rob. If ...
