With all what metatrader does, those are not bugs any more - otherwise we would have to call it metabug - it is hard to find a part that does not have bugs. It is simply metatrader. It tells it all

There is a HUGE problem (error, bug, whatever they want to call it, but it most certainly is not an improvement or a "feature") in build 840 :

Build 788 : one opened chart, no indicators = 22MB

Build 840 : one opened chart, no indicators = 164MB

Almost 8 times more - for a blank chart, same symbol, same time frame, same max bars on chart set - 5000 in both cases. Thank you mt

Build 842

Memory issue still not solved

Issue with a cancel button on built in indicators seems to be solved

It does that with all the built in indicators (even if you use them from the navigator) Custom indicators work OK

I didn't agree... Many Indicators not given Correct the Signal

And more the Issued, DATA in 4 digits MT4 is 'Defferent' with 5 digits MT4

That is a problem that indicators that are written for 4 digit brokers must be rewritten to be able to work with 4 and 5 digit brokers

The problem I was explaining was that when you wanted to attach a built in indicator to the chart and you pressed cancel, in build 840 terminal closed.

I can not get a hold on how build 840 uses memory

There is no rule what it does

It is easy : in average 5 times more memory usage. When back testing, it hits 0.5GB for a mere 3 month back test (compared to 10-20 MB with previous builds). All in all : they did what they wanted - a disaster

Yes, I see

I can not test when I download the whole history for eurusd - the cpu and memory overload is disaster in that case

Maybe it will be corrected in build 999 (along with all the new bugs)

Using bitmap resources can change behavior of some common objects in metatrader

Here is one example how one indicator looks like on a chart looks when no resources are used :

And here is that same indicator when resources are used :

There are some more things happening, but the essence is that using resources can and is affecting the way how other things are treated by metatrader. In this case it is visual appearance, but it is not sure that it is just that (this test was done using build 788 but similar results were when build 842 was used). That bug existed starting from build 600, then it was corrected, and now it seems that it is back again with the new builds

___________________

Also, when the chart is not focused, some functions like ChartGetInteger() are returning wrong values for some properties. Do not count on accuracy of those functions when they are not focused (it is same when build 842 or build 788 is used)

Again they are doing the same old one step forward, five steps back
