capital_base can't be covered using multiple currencies

[STOpandthink]

I have a problem where I can't start my trader right now because it crashed after a buy trade. So my portfolio is 50% USD and 50% BTC. I want to start the trader that can trade that entire portfolio, not just the available cash (or available BTC).

It occurs to me that probably this should be covered by algo_namespace. (The algorithm should remember the trade and count the asset towards capital_base.)

It's possible this is already being done. I'm running into a weird issue where I'm trying to run the same code on two different machines. On one everything works okay, but the other gives me this error: catalyst.exchange.exchange_errors.NotEnoughCashError: Total usd amount on bitfinex is lower than the cash reserved for this algo: 0.0 < 800.0. While trades can be made on the exchange accounts outside of the algo, exchange must have enough free usd to cover the algo cash.

I've tried clean-algo with no improvement. Are there files or state being stored locally on a machine aside from this?

Just run into the NotEnoughCashError again. I have 900 USD in my account, my Enigma says I have zero. I tried catalyst clean-algo, but it doesn't help. It happened after I was changing quote_currency, but also when I went from paper trading to real trading. I'm not sure if either is related.

One more piece of info: I just recently sold BTC to convert it to USD. So I'm hoping it's a caching issue and will resolve itself soon. Changing namespace to a new one didn't help, by the way.

Oh wow, I tried running it in paper trading mode and it fails too. I don't even understand how that happens, given that in paper trading mode you're supposed to be able to set any amount AFAIK.

Btw, here's the error stacktrace:

Ah, this was my mistake. My money was actually in USDT, not USD, so I had to specify usdt as quote_currency.

The only thing that's left is: It would still be nice to initialize portfolio using multiple currencies.
