AUS races liquidity - How to check

[StuT]

Hi there,

This might be a tricky one to answer but I'll ask anyway.

I use excel triggered betting on AUS horses, both Harness and Gallops.

However, mainly on Harness races I have noticed that there can be massive jumps in the market right up until the off.
The jumps in the market seem to be on the red hot favourite and where there is poor liquidity in the market. This is where big gaps can appear in the market, which is not ideal for me.

I intend to skip these races.
I need enough liquidity to not have these gaps present,

My question is how much roughly in Total Matched (Cell B3) would be seen if the market has decent liquidity at the scheduled start time?
Or is there something else I can check

Thanks.

Only you know how much liquidity is enough for you to operate, our versions of a liquid market might vary drastically. If I'm offering prices low liquidity might work for me whereas taking prices it won't . Betfairs own data files will give you a rough idea of the sort of liquidity courses attract.

What you need to do is decide how much liquidity YOU need for whatever strategy you're using to work efficiently. If it's just gaps in the market that worry you they're easily counted just by seeing how many ticks are between lay/back price points or back 3 to back 1 prices etc. You can add the offer amounts available at the prices you want to play etc check lay/back market %'s to see if markets are fully formed.

Thanks again CS.

I will check the Total Matched for volume along with the Back and Lay prices for any gaps.

Much appreciated.
