Any chance your new API key doesn't have the correct permissions?

[TradeCrafter]

read info, trade limit and trade market enabled,new api and secret just created

[TradeCrafter]

was a typo error on the api key, and now seems to be running but showing other errors

TypeError: unsupported operand type(s) for *: 'NoneType' and 'float'
2018/04/30 10:36:13 AM - ERROR: Failed to fetch Bittrex market summary for the BTC-USDT market.

what should be expected as an correct output ? the lines bellow keeps repeating on my powershell terminal

[JPStrydom]

In your app-data.json file, does your pause time have have the following structure?

{
    "coinPairs": [],
    "pausedTrackedCoinPairs": [],
    "pauseTime": {
        "buy": "null or a number",
        "sell": "null or a number",
        "balance": "null or a number"
    },
    "previousBalance": "null or a number"
}

i.e. Do you have the "balance" key in your "pauseTime", and do you have "previousBalance" as null or as a number?

[JPStrydom]

I just pushed an update that should hopefully fix your issue. Please check it out and lemme know if its :)

[TradeCrafter]

nope... my app-data.json has the same structure, but numbers, the previous balance is null... downloaded the new and no changes... remains the same error

[TradeCrafter]

what is expected to see when works ? it needs to let it running,i know but i wanna know how it behave

thanks for the fast repply, i am looking for a nice trading bot

[JPStrydom]

So this functionality is purely to send balance summary slack messages. If you're not using the slack integration, or just want to leave out the balance notifications, I'd suggest just deleting "balance" object from "pauseParameters" inside your settings file. So it'll look like this ->

{
    "sound": false,
    "tradeParameters": {...},
    "pauseParameters": {
        "buy": {...},
        "sell": {...}
    }
}

The issue here is that Bittrex is failing to fetch the market price (which it sometimes does). It shouldn't crash the program (if it's crashing, please let me know), and it shouldn't cause any issues - but I'm looking into a fix now 👍

[JPStrydom]

Just pushed the fix. Please let me know if it works.

[TradeCrafter]

now just dont run... it gives this message on command line:

PS C:\Users\Leonardo\Desktop\Crypto-Trading-Bot-master\src> python app.py
Please completed the settings.json file in your database directory

i am using your given example of settings.json

[JPStrydom]

Please have a look at the README and make sure your settings file is correct. The bot needs those configurations to operate correctly.

[TradeCrafter]

i have looked, have edited app.py, got it running, but without some parameters, but deleted and downloaded again,created new APIs and settings file like readme... but the error seems the same:

i am using windows 10 but all pyhton scripts mostly works fine to me

thanks for the response, and lets get it running !!

[TradeCrafter]

i am giving it up bro...now it replaces the content of json files with default values...

[JPStrydom]

If it's overwriting the JSON file, it means it failed to read it and there's most likely an issue in your files formatting.

As for your initial error, it's still a Bittrex issue, but I believe I know how to work around it.
