Volume Spikes

[RonObvious]

Hi,

I've attached an image taken just before the off from the 6.45pm at Wolverhampton this evening and I'm hoping somebody can explain the difference in volume amounts.

As you can see according to the Bet Angel advanced charting a lay order of around 5k has hit the market sending the price out but on the Betfair chart at the corresponding time the lay order is only around 1.6k.

I've heard people say the BA charting will show double the amount that the BF chart does as its showing the back and lay side so effectively double the actual order that was placed but even if this is so in this instance the order on the BA charting is at least 3 times the amount.

I've seen this happen a lot and would be grateful if somebody could explain it to me as I've no idea how much was actually staked.

Thanks

I beieve it is the back and lay price matched together...

Even if using the same refresh times are being used for both charts they could still be small differences if there both not in 100% sync.

ie; each chart is refreshing every 5 secs and showing the amount matched in that period
Advanced - 18:41:05, 18:41:10, 18:41:15 etc
Betfair - 18:41:02, 18:41,07, 18:41:12 etc

Don't trust Betfair charts, they are a not a sequential plot whereas the advanced charts are.

[RonObvious]

So from looking at the two charts what is actually the size of the order that hit the market?

£5k/2 ish

£5k/2 ish

Ok last question is that a 5k straight lay bet or is it 2.5k on each side of the book as I've heard somebody say?

£5k/2 ish

Is there any reason why BA shows the sum of both sides, as BF does, rather than just he amount matched? ie 5k not 2.5k. Is it just to make comparison with BF easier? Either way is fine, I just wondered.
