Trade Profit calculation

[david77]

hi
In the Bet Angel One Click screen can anyone tell me how the Trade profit figures are calculated using the example
I put a £10 lay on a horse at lay odds of 3.55
At the off the back price falls to 2.00 giving a Trade Profit of -£7.75

Stake multiply by entry odds & divided by current best exit odds
Example; A back bet of £50 @ 7.4 and current odds to green up with a lay bet are 3.15
£50 multiplied by 7.4 divided by 3.15 = £117.46 lay bet requied at these odds

Thanks for this
What formula applies when the opening bet is a lay which requires a stop loss
