Please check your NXC orders. Did you get filled? Thanks!
Same pattern again as with MAID:
1. Buy order not getting filled at first time, so the sell order was not set too (no coins = no sell),
2. After some time buy order filled, but sell order not triggered
ERROR Not enough NXC. SELL order sent BTC_NXC at price 0.00008125 357.210000 coin for 0.02902190 BTC
SUCCESS 34096xxxx BUY order sent BTC_NXC at price 0.00005585 358.100000 coin for 0.02000000 BTC
I understand the cause (too many orders) but so far it doesn't look good.
UPDATE 30/March.
Refactored the buying mechanism, bot allows bigger spread to buy so theoretically everyone will be filled on the orders. No worries, Poloniex will fill you at the best sellprice, however bot tries to buy a bit higher.
I was late by 10 mins uploading the new version.

Sorry for that. Orderbook is very thin on NXC.
