Not enough COIN error when transferring between exchanges

[Scorpic1]

With pl-rewrite branch still have problem with re-balance coins to exchange like in #11 SC coin. Now bot make transfer all coin SYS to other exchange. I did not know why bot did it.

I noticed this only after an error below:

21:13:24: Calculated P&L: -0.00000028

Maybe problem in logic re-balance bot. Maybe problem in logic re-balance bot.

Why get this is error? 21:13:25: Error during main loop: [POLONIEX] API error response: Not enough SYS.

The actual problem here isn't fixed at all. I'm going to delete the off-topic comments to make things clearer.

I suspect #39 may be the underlying bug that causes some of these errors to occur...
