Is there a way to display the traded volume for each of the runner prices?
Like where it shows the runner's price say 5.8 £12, that it could also show 2.2k for the volume that has already been traded at this particular price. You can get this information next to the betfair chart usually, but a live update would be awesome.
If this data does not come as standard via the runner price in the API, then maybe it could be updated less frequently than the prices, say every 10 seconds or so.
Hi, from the Options -> API you can request to download the full prices from Betfair with the exchanged amounts. This can be useful only if you want to place large bets using the criteria "Bet Price" with "Stake Amount". But currently, all this data is not yet visualized in a proper ladder.
Yes, the prices are recorded in tbl_BFPrices, but if you need only the best 5 prices BACK and LAY is more practical to get them from the table tbl_Races_Horses (B1_price, B1_amount, L1_price, etc..)
