Describe the problem

I'm having this error on Binance:

An error occurred { Error: binance {"code":-1013,"msg":"Filter failure: MIN_NOTIONAL"}
at binance.handleErrors (/home/user/zenbot/node_modules/ccxt/js/binance.js:1185:31)
at response.text.then (/home/user/zenbot/node_modules/ccxt/js/base/Exchange.js:648:18)
at <anonymous>
at process._tickCallback (internal/process/next_tick.js:189:7) constructor: [Function: InvalidOrder] }

I have checked through the issues pages on github and could not find a working fix. I have updated zenbot-stable, updated ccxt, then I went to zenbot-unstable with an updated ccxt (updating ccxt was one of the recommended fixes). As a last ditch effort, I purged everything and started clean. Dumped the database, deleted zenbot, uninstalled mongodb and nodejs, removed all config files. Then I reinstalled mongodb, nodejs, zenbot-unstable, updated ccxt, and I am still getting the same errors.

Sims work fine, paper works fine, live trading works until it wants to trade and it throws up that error. I started trading 2 ETC with BNB, they have similar values at this time (2 ETC = ~1.7 BNB), so it isn't a minimum trade issue. Plus, the buy_pct and sell_pct is set at 99.

Although I am using a custom strategy, this also happens on rsi -- my go-to live trading test strategy.

Any help would be nice.

It is a minimum trade issue, just not a regular one.

"Filter failure: MIN_NOTIONAL" means Zenbot tried to create an order with a notional value (= price * quantity) below the minimum.
Zenbot does not support the notional value concept (it try to use a higher min_quantity to compensate). I'll try to work on it, but I can't promise anything.

Also, I think Binance has done some slight modification of their API a few days ago. It may explain why your the first to hit on this bug.

Well, another reason why I didn't think it was a minimum trade was that I can buy and sell just fine on binance website. I even tested small values to trade and it said that the minimum for that pair was 1. Should I throw in a little more ETC to see if that would work (all I have left is 0.25)?

@rountrey I've fixed it. Wait until the pull request is merged (or clone my branch if you're pressed)
With this, orders too small will get ignored instead of triggering an error.

It will not resolve your problem since orders will not pass. I would advise you to use more than what's you have put if you don't want to keep running into this kind of troubles.
0.25 ETC worth less than 1$, which is IMO the bare minimum to put an order.
