So the Quickscanner will loop notifications on low volume coins a lot. these are mainly those account builder coins that dont have a lot of trading going on but have large moves all the time. the scanner will pick a few it likes that dont really do much moving and alert you about them all the time. even with no trading going on. in my case PRO/BTC and GNX/BTC on HITB are driving my scanner up a wall but the price is still at a standstill and noone traded yet.
to reproduce: change your quickscanner settings to either HITB or BTRX and set your pairs for 1000 USD vol. rise/drop to 8 and FF to 10
Like this one, last trade was 18h ago and it poping alerts whole time like crazy
Yes it seems that when the quickscanner catch a price change that is according to your setting and then price doesn't move - no buys/sell in the orderbook for hours, alert gets looped and pop every 20-30 seconds for that same price move.
