Hi Gunthar
I only stopped/closed instances of the bot for currency pairs which had no open orders.
Now I have a few altcoins in my account which the bot seems to have bought but did not put in a sell order in. How do you think that came about?
AS already explained previously in this thread, that's a normal behaviour: the bot doesnt put ALL coins to sell orders if there is not enough ask/bids at that price and also to not engulf the "onOrder" balance of type "SELL" so, your bot, would keep buying if market conditions are met (otherwise you would reach the "We used enough balance on this pair..." message too early)
Please dont stop the bot nor trade those coins manually: by the order number, the bot is able to store the BUY price and to put a SELL price for those coins soon as the market conditions are again with enough ask/bid volume for that price.
Thanks!

EDIT: i understand now it is not your intention to trade those coins anymore. So you should calculate they buy price to put a sell price manually. You can do it by bot logs or you can just go to this page of poloniex and see the average BUY price for that coin and do your maths
