If i had placed an initial back bet at say 5.3 because there wasn't much money there. Then wait until the odds get 5.2 and only place the lay bet there if there was a large chunk of money behind me at 5.1. If not then I would cancel all the trades. Likewise if I placed the lay at 5.2 and my money at 5.3 wasn't being taken then I would move my trade at 5.3 to 5.2 to scratch.
It sounds simple and is. But like I said previously, you have to concentrate and be quick to either cancel all or scratch.
Would be ideal to automate as you could then just run it on 1st, 2nd and 3rd favourite. But so far I have never really figured out how to get the scratch trade correct.
Maybe Dallas can knock something up.


I wouldn't try it on the Greyhounds unless you have a large supply of adult nappies.
