Error Saving Period - Githubissues

Thank you so much for your work on this bot.

I've been running this fine in paper mode without error for a couple of days. I woke up this morning, and found this error:

Based on the line numbers, I believe the error should be: error saving period. Anyway, I just wanted to get this reported. If I get a chance I'll dig into the code some more.

I was going to get you a version (zenbot --version), but when I ran it, I got this:

warning: mongodb not accessible. some features (such as backfilling/simulation) may be disabled.
4.0.5

Trying to restart the bot with this command:

$ zenbot trade gdax.LTC-USD --paper --currency_capital=500 --enable_profit_pct=10 --profit_stop_pct=4 --trend_ema=36 --sell_rate=-0.006

Give me this output:

warning: mongodb not accessible. some features (such as backfilling/simulation) may be disabled.

Seems to be that my mongo instance has crashed. I find that odd since I have a pretty beefy server that otherwise exhibits no issues. Maybe this is the first sign? 😟
