don't worry about zigzag. it will be added as standard(not custom) indicator. but i don't know exactly in what time

Slawa - could you please convert this MT3 Indiator to MT4 for me...? I use it every day.

Thanks

Hi Slawa,

I also want to delete the middle line in bollinger bands but i'm a bit of a technophobe so what do I do with the "code" please?

Also I want to add the following Bollinger Band to my chart (10/1.9). Would this be done by inputing 10 in the "Period" box and 1.9 in the "Deviations" box?

Looking forward to your response and thanks in advance.

Wink
