Everything you said is correct:
With the Bloody Mary refactor of BUY/SELL orders handling, since the bot uses "onOrder" balance to spot the point you bought enough of that pair, i only place on SELL what the market is able to receive, leaving on Altcoin "avaliable balance" what is left. Bought price is stored with the orderNumber to calculate the sell price of those coins later on.
People were used to see available balance and on order balance of altcoins, perfectly equals. That changed!
Dont stop yoru bot for that....
