Possible Features for Signal Orders from Providers

Hello, I wanna reduce my risk on my signal providers’ orders.

I am thinking of this strategy.

I want to customize my entry price based on Signal Providers.

Instead of market execution which opens an order instantaneously, i was thinking of a buy/sell limit order.
For example, if the signal entry was 1.00500, i want to put 1.00300 which is 20 pips below the entry of the provider, and this becomes a limit order instead of market execution.
