Back And Lay Trigger

Maybe this idea could be one of the free triggers of the MFP already I do not know?.

I have noticed that not very often that the back price is longer than the lay price, and this would be a certain profit every time.
Could a trigger be built to continuously scan the back and lay prices on Betfair and when the back price is longer than the lay price to instantly place a back and lay bets to secure a certain profit with every one of these bets?.
If so I would be prepared to pay some clever coding person to write the code for me so I could add this strategy to MFP.

This is the X-feeder forum,  where did you notice the anomaly you describe.  I don't see how it is possible.

I have been getting one free tip every day for a while now and have been loading these tips into a bot's back instance and lay instance making sure that both instances fire
off bets at the same time 60 seconds before the off. Last Friday 14/6/19 the prices obtained by the bot were back 9.00 and the lay 7.40 making his tip for the day a sure
green -up bet for backing and laying.
So this seems to prove that it is possible to have a trigger to scan both back and lay markets on the BF exchange for such opportunities and place both back and lay bets
together while these prices are available, all in auto mode.
Such a trigger is what I am after?.
I like complete auto mode which would operate 24/7, instead of being chained to PC hoping for one these bets to appear.
