Detecting and excluding outliers and market manipulation is an important data processing task, especially in small and (somewhat) intransparent markets.
We calculate our cryptocurrency-spot-prices using 120-second moving average (SMA). In order to create reliable pricing, we also exclude data points & sets that lie outside of an acceptable range relative to the interquartile range of all data points.
This will be constantly improved over time with crowd-driven algorithmic improvements from the traditional financial space, taking into consideration that high volatility is a part of the cryptocurrency space.
