MT4 Platform slows down

Hi @all,
I have created a new chart template with several Indis running. Since this metatrader slowed down a lot.
Often it freezes for several seconds....
When looking on my task Manager it looks good as I interpret the things I see.
Is there a possibility to find out which of the indis does cause this slowness?
Thanks in advance.

I feel your pain... I have alot of indicators, custom code, expert advisors, and once in a while I have to do some performance tuning...

Here are some tips:

- First back up your profile and save a chart template to backup your current Charts...

- Tools >> options >> Charts Check the Max Bars in History and on Chart. change to 5000 and check performance
- Terminal >> Check your Experts and Journal Tab for Error messages.
- Objects Browser (CTRL-B) - check how many objects you have. Try deleting them all. I find that after 5000 chart objects performance lags.
- One by one remove indicators to determine the bad boy... then focus on the code in that indicator.
- If that doesn't work then try creating a new chart, adding your indicators one by one to figure out which one is the culprit.

Viel Glück!

Hi PMak,
very very thanks.....I did as you suggested and checked the objects box: every chart (8 majors + gold) had about 65.000-78.000 objects! Then I created a new profile putting 12 different charts on it. Every chart got 1 different of my 12 indicators. Now I wrote down the no. of objects on each chart and checked again after 5 minutes. That way I located the bad boy. This indicator grows the objects by about 1000 + each 5 minutes! Thus I put together the other 11 indis on my 9 different charts without this bad boy. Now running as fast as before.
As I don`t want to miss this indi I put it below here. Perhaps you (?) or someone else may check the code to optimize this? But I fear its not possible as I have only the ex-Version, not the mql....
Thanks a lot.

Without the source code you won't be able to change the indicator but you could create a simple script that deletes all objects and run it manually or create a second indicator that every 5 minutes or so deletes all the objects you dont want.

Ah ok, thanks for the hint.
But without coding knowledge....
