My calculation of your approach. 1500 subscribers, price 30 credits (minus 20% then 24 $ for me). 1500 x 24 = 36.000 $/month. 36.000 / 30 = 1200$/day. Anyway it is much more then limit of 500$/day.
Thanks by help!
I adjusted the values now!
Yes, 500 credits limit per day is very inefficient for high income services.
In addition, to the fact that MetaQuotes can gain income on the amounts held.
MetaQuotes should give some formal response to it's customers in order to enable customers believe in their system and support it.
