Is the paper trading by QuantOpian also shutted down?

I thought the QuantOpian will just shutdown the live-trading connected to the brokerage like IB. It seems now the paper trading on QuantOpian is shutted down as well. It that true?

I'm having the same issues running backtests. Its just not running. That was unexpected!

Paper trading has not been shut down. It doesn't run on the weekends -- the market isn't open.

I am running a backtest right now. I do note that the "Live Trade" button is grayed-out but I'm also getting a note that for the algo, I have some deprecated API elements, so maybe everything has to be up-to-date to live trade?

Edit - I was able to launch a live trade algo, even though I got the grayed-out box and the API deprecation message. Maybe Q was just doing maintenance?

Hi Josh,

The reason why I ask such a question is because there must be a buy-in on Friday. But this didn't happen by the paper trading.

Here is what I get from my back testing:
... 2017-11-10 14:45 before_trading_start:117 INFO XXX_SMA: 92.2202

One can see there was a BUY of SSO at 17:00 (German Time)

And below is what I see from the paper trading:

There was no any BUY. (I've replaced some sentive data with XXX)

Maybe QuantOpian could have a check?

In response to Josh...

Backtesting is down on weekends? That wouldn't make much sense. The purpose of backtesting is to use price history to validate your trading algorithms, which doesn't require live or open markets.

Backtesting isn't down on weekends. You can merrily backtest away. Paper trading is a simulation 15 minutes delayed off of the market. So that doesn't happen on the weekends because US equities market hours are Monday - Friday.
