PHP SQL Algorithm

Hi all,

 

I'm currently working on a bet matching algorithm (similar to Betfair) but am not quite getting the logic right.

 

So far (in psedocode I have):

 

========================================

 

Make new Bet();

 

While new Bet isn't matched (using 'match for count)

{

Find any potential matches

if num of rows > 0

{

while potential matches exist (using 'match')

{

Find least recent match

Create new record in matched table()

Increase 'match' count on back table

Increase 'match' count on lay table

}

}

else

{

break;

}

}

 

========================================

 

It needs the potential to match 'parts' of bets against each other so that users can cancel bets or parts of unmatched bets. Does anyone have any ideas?
