Market freeze on fast price movement
« on: December 11, 2014, 03:11:26 AM »

Are the price movement restrictions still apply in the actual version of the market engine?
(i remember about certain percentage change will freeze the market in order to give time to traders to reorganize their orders)

Thanks xeroc, i was aware of those two restrictions, but i remember BM (some months ago) writing about this.
I don't know if this was implemented or it just product of my imagination....

Btw, in the case of valid_feeds < 51 the new feed is the average price of the last hour right?
(valid_feeds = published less than 24h ago?)

I believe the market depth requirement was kicked some versions ago. BitEUR for example is happily trading with nearly no depth.

Oh . Maybe I missed that ... it became quite diffixult for me to follow everything happening here ::)

The price is not averaged over the feeda but uses the MEDIAN ... feeds expire after 24h .. not sure if longs can still trade then .. but shorts stop if less then 51 feeds are valid
