Drip lay FHG and O0.5 dependant on back price of Over 2.5 goals

Hi,

I paid for a trigger to be developed but upon reviewing this forum it seems as though I’ve paid for a service that no longer exists! 

As such, I’m seeking help to develop a trigger(s) to develop the following strategy. I have tried myself but I’m struggling!

Record the back price of UNDER 2.5 goals price at 7am
At 5 mins pre-kick off, compare the back price of the UNDER 2.5 goals versus the price at 7am, if it has drifted and the price is between 2.0 - 2.99, go
on to the next step.
(If this criteria is not met, NO BETS to be placed).

LAY under 0.5 FHG (first half goals) to win 0.5pt at 5 mins pre kick off
If 0-0 on 10 mins LAY under 0.5 FHG for a further 0.25 pt
If 0-0 on 20 mins LAY under 0.5 FHG for another 0.25 pt

STOP at any point a goal is scored

IF 0-0 at HT,
Place another LAY bet on U0.5 goals at 50 mins for 1 pt
Place another LAY bet on U0.5 goals at 60 mins for 0.5 pt
Place another LAY bet on U0.5 goals at 70 mins for 0.5 pt

Again, STOP all triggers if a goal is scored at any point 

If a goal comes in minute 45-49, I accept the loss from the first half.

Also note that 1pt is defined as default lay_amount.

I need the ability to run this trigger on multiple markets at the same time. Also, if possible, I would like the trigger to refresh more frequently at the required minute of each game, and slow down significantly when no action is required. 

I think this should be fairly easy to do but like I say, really struggling to make it work. 

Any help gratefully received. 

Thanks
