Yes, many testers said about it.
In was many suggestions concerning website statistics using dollars calculation in additional with pips calculation, using some sort button for buyers to select the signals with/without stop loss - stop loss value - DD and so on.
All those suggestions were delivered to the developers. I think it will be improved.
Just for now we need to receive the most stable version of RAS tool first and after that the developers will implement all the ideas and suggestions (there were a lot of ideas/suggestions and so on - all of them were sent to the developers).
Calculation the profit in deposit currency in case of lot-multiplier = 1: it was one of the first idea which all the testers made on this thread and by PM.
But it may be better to use 0.01 lot size instead of 1 for example. Because if your client need 1 lot size (and your starting lot size is 0.01) so he will use multiplier = 100 and he will receive 1. Because many members will subscribe to many signal providers and they will use lot-multiplier in the settings to select lot size according to their deposit.
I am testing as a buyer. For example: if you are using lot size = 0.01 and I (as a buyer) need 0.05 so I will change the settings in my RAS tool (buyer's mode) to lot-multiplier = 5. And in this case I may subscribe to the other signals on same account depends on how big my deposit and how much should I pay monthly.
Some people asked by PM why I am using this terminology: buyer and seller

Just because it is the settings in RAS tool:
buyer = false or
buyer = true.
It is just a technical terminology. Because the member who are making free signals are still the seller according to the RAS tool settings (buyer = false in the settings).
