Placing stop loss according to filled entry#547

It is suggest to add a way to set the stop loss based on the actual filled entry price, using the same percentage as given in the signal?

For example:
If the signal says entry at 1.100 and stop loss at 0.900 (which is about an 18.18% difference), but my order gets filled a bit lower than 1.100 — can the stop loss automatically adjust based on the filled price, keeping the same percentage of the signal or a custom precentage set by the user?
