Exponential moving average - Values

[rbb1986]

Hi,
I am aware that exponential moving averages can be calculated in excel and sent back into betangel....however please could you help me to find the correct calculation for betfair?
For example I am using advanced charting and an EMA line for the lay price at 1 second intervals, and 600 data points - how does Betangel arrive at the value that is plotted on the chart? Is there a way to see this exactly within BA?

The reason for this is to allow this to be sent back into BA as a stored value and subsequently used in automation.

I am setting out to work this out myself but was just wondering if anyone already knows the formula BA uses exactly, or if this can be identified/read from within the scripts of the program anywhere?

Thanks
Robin
