Clearing Comments

[Trader3487]

Is there an easy way to clear a comment (so that it disappears from the chart) after it no longer meets condition? http://fxdreema.com/shared/OOOCdZJNd

Try with the other comment block with content "". But I think this block is not very good and I will probably do something with it.
Or try with Custom MQL4 code with this content:

Comment("");
