'angle' in 'on chart event data'

[spaniard]

Hi Guys,

Anyone know if there is a possibility to use 'angle' in combination with 'up' or 'down' instead of 'above' or 'below' ?
I want to use it to take trades of the bollinger band middle line.

Or is there any other way to identify a slope?

thanks in advance,

regards,

Fabian

@spaniard I join to your question. I never knew how this 'angle' thing works. Has someone tried it? How does it work?
