Hi,  I noticed a weird thing GunBot did today.

It bought at a price, then a minute later sold at the same price, then a minute later bought at the same price again.  A loss in fees.  Why would GB do this?  Is it a bug?

For info, I'm using stepgain buy/sell strategy with lvl1 buy at 4 and lvl1 sell at 2, 20 second delay and using community proxy 0.9.8.

I did notice a weird error which may have been involved in this strange behaviour, but I'm not a GunBot expert so can someone please help me here?

Below is the logs and attached is the buy history from Poloniex:

Re: Buy then sell then buy at same price within only a few minutes
« Reply #1 on: July 23, 2017, 08:35:31 PM »
I've been running GunBot since the beggining of May. This has also happened to me on a few occasions, unfortunately.

The new release should fix those issues, it has to do with 422 and a buy/sell callback that the bot didn't received, so it thinks it hasn't bought yet. I see you are using the proxy, so this is definately a bug and nothing to do with 422 problems.

Anyway, in 5000+ trades so far it has happened 10-15 times (a 99,75% sucess rate ain't bad, is it?)
