Graph

[redtra]

On the Betfair graph which shows price / volume over time, I can't work out what the time interval is. It looks as though the graph shows all of the trading but sometimes seems to change shape quickly as though the time interval is changing. The bottom line is divided up but into what?

there is no time on the betfair graph, it's volume and price since the market formed..hope this helps

thanks Herbie, yes that is very good to know. It explains why the graphs look different in the mornings compared with later on.

watch this ba vid. it explains the way that betfair compress the time scale on their charts, and what all those little lines at bottom represent/mean.

and another one - you will not get a clearer one than this - peter as a betfair chart side by side with a ba advanced line chart - you can clearly see the effect the compression has
