Hello i purchased 2 licences from gunbot.shop - bittrex works but bitfinex brings me the following error:

Loading config...
Loading exchange - bitfinex

Errors

and another two questions -
1.how can i tell the bot to use always the max for example btc that i have - trading limit over fund? for example i have 0,045 btc so i set 1,0 btc?
and
2.what happens when i user bb strategie and the market crashs - when profit is set for example to 2 % it never sells below the last buy right - not importend what bb high and low is set - what happens when i stop the bot and start it again - does it remeber the last buy level?
3.how can i set the stop limit in the way that it never sells - not important the loss is for example over 90 %..

thx for your answers

1. you can't. If the trade limit is not met on your account, it will not trade. it will message "waiting to cash some btc" or something similar.
2. it does recognize the bought price. but if for any reason it can't find it, it will message you. then you can put the bought price in the override.
3. not sure. best remove the pair from the current setup?
