This does not make sense:
..my indicators failed to update and they just went blank.
The studies will not just simply go blank if they are currently displayed.

This actually does not make sense either:
Price information was continuing to update and candlestick bars continued to form...just no indicator updates.

The general reason though, why you would see the price box on the right side of the chart update but not studies, until the historical data is downloaded, is a lost market data connection. Refer to:
Intraday Chart or Chart Bars Not Updating | Blank Intraday Chart | "Currently no data to display" message for Intraday Chart: 3.1 - Historical Data Being Downloaded

So you had an Internet connectivity problem which also confirms why you had the trading issue.

The other issue with trading definitely would be related to a connectivity issue.

This would be related to the parent stop order, not being acknowledged which would be due to a connectivity issue:
..I placed a stop order to go short (with attached orders, one order to buy at my target and one order to buy my stop loss level). I have done hundreds of times without a problem. The price moved higher and my order to enter the market via my stop did not get triggered/filled...so, I tried to cancel the order right before I placed a new short order at a better price.

And once that order filled, you would not be able to cancel it. You could only flatten the position and cancel the child orders.

We really have to verify everything that you are saying from the Trade Activity Log because there are some things that are not really making sense. For example, if you are able to get another stop order put in you should then be able to cancel other orders, or flatten the position. And cancel orders.

Anyway, when you have a situation like this, this is the procedure to follow:
Overview of Trading: Handling Non-Responsive Orders Due to Lost Connectivity

This is a reliable way to get the position flattened and cancel working orders by sending a single command to the trading server.

We would have to suspect the core problem is not getting an acknowledgment for submitted orders and that prevents them from being canceled. We will see if we can improve upon this, by putting the cancel request as a delayed action pending acknowledgment of the order, if it is not already. We will look into this.

Only use a wired reliable connection:
If so, is there a fix?
