The candlestick chart shows an amount of £63k, the price/volume chart just over £30k (about half of what the candlestick records)
Differences in Chart Volumes?

I was wondering why the two charts below show different totals for the same large order that went through the market.

possibly, but if that was the case shouldn't the chart with the smaller refresh rate show a smaller amount, not the other way around?
We don't how Betfair calculate the volume on their chart but on our charts we make the volume by subtracting the current volume from the volume reported on the prior refresh. It looks like Betfair are simply taking actual money staked, rather than volume reported. Matched bet volume is double the nominal trade value.
