How to use the adjustmentFactor

[NickyG]

I would like my bot to keep a short term log of the prices of the runners in each horse racing market so that I can detect price movements over time but am confused about how to use the "adjustmentFactor".

Say I log the prices of each runner, then a runner is removed causing an adjustmentFactor of 20, would the next set of prices that are returned already be reduced by 20%, or would I have to do that manually,and therefore adjust the earlier prices that have been logged as well?

The adjustment factor applies to prices prior to the removed runner. The adjustment factor of the removed runner is applied to the previous prices of active runners.

Future prices do not require adjustment.
