[ X] bug report
[ ] question about the decisions made in the repository

Action taken (what you did)
I'm trading using Gekko UI on Kraken with the EUR/ZEC pair and it used to run fine, but the bot crashed after almost 2 months. I changed my strategy and the tradebot constantly crashes.
I tried to change the minimum amounts on /utils/genMarketFiles/update-kraken.js but it didn't change anything.

I have the same problem on the ETH/EOS pair on Kraken. Some other bots run on Binance and I have no problem. I use the develop branch and I'm up to date.

Expected result (what you hoped would happen)
Trade if the minimum amount is available, otherwise do nothing.

Actual result (unexpected outcome)
The tradebot crashes and disappear from the UI.

Hi, maybe this workaround helps you: #2083
There's an open PR for this, but it has not been merged yet.

[glegarand]

I updated the plugins/trader/trade.js as mentionned, but now I can't see my trades in the UI.
I have a buy ETH/EOS order recorded on Kraken this morning, but no green dot nor stats on the UI.

[H256]

@glegarand Unfortunately this seems to be another problem that could be fixed with this PR #2181 , though I have not tried it out, since the bot trades fine and I'm analysing the logs instead looking at the ui.

[askmike]

Note that there are some bugs with the trader which I am currently improving, see #2118. But yes, @H256 is correct that this bug is fixed with #2181. Please download the latest develop branch from git to get the fix.
