CCP disabled history endpoint and atm no ETA available when this will work again. This endpoint was used to ddos server. Bot uses old history file now. History file is used to know average trade volume per day for the items. Trade volume does not change a lot, so old file works too. The only problem is that trader does not work with new items.
If you want to create fresh history file you can add all items to the
market exporter list. Deactivate trade function and order installer functions and start bot selecting "evetrader" as algorithm. Bot will export all data in game and this will take 6+ hours. We did this long time ago when API server did not exist
I did not test this functional. Nobody used it since API worked well. In case of a problem report bug and I will fix.
