Hello.
About signal providers.
I have a question, and a request.

1) I want to register, as a signal provider.
To give to other traders, the possibility to copy my trades.
I want to ask, after I write the signals subscription price,
is it possible, to change this price anytime, for example after days, or 1 month, or more ?

2) Please make the possibility, to write this signals subscription price, also as a percentage of the profits, of the traders, that copy my trades.
Example: Signals subscription price= 30% of the profits, of the traders, that copy my trades.

Thanks.
