At the moment I am setting up/migrating to m30 charts and multiple pairs. Thus alerting from the dots are coming up for me.

Setting filters to alert remotely or local via email etc. across multiple pairs is showing to be a hugely significant advantage.
First of all, compliments and thanks on creating such a powerfull and usefull feature.. :-c
I have come across a situation where i would like to take advantage of certain black dot "conditions". I have turned off "against purple" and reverted to AO level filter to discriminate these.
From the picture, top left, the circled powder-blue dot was a blue dot filtered by AO value, away from purple. The following red dot is a successfull black dot turned to red alert.
The 3rd circled blue dot, which was a black diamond against purple, i seem unable to turn it to a powder-blue via AO filter, thus giving me an unwanted alert.
My question: It seems that dots against purple does not respond to AO level filter?
Please advise if i am missing the boat or do u see the same.
Thanks.
Regards
Herbert
