I've been using Quantconnect for about a year now and am very pleased with its functionality. I am wondering if it is possible to output more characters/lines when outputting to Console, especially when running Live. I am running a semi-automated intraday strategy on the minute timeframe, which gives me trade ideas that I can then manually inspect. I've noticed that when running Live, the Logs are delayed usually by about 30 seconds to a minute, but the Console output seems to be in real-time. However, there also seems to be some line (or character?) cap when outputting things to the Console, where the remaining output gets converted to “…” like this:
Remaining output is converted to “…”So when using the Console I can only see 2 or 3 trade ideas per minute, when sometimes there may be more (e.g., up to 10 or so). I can see them in the Logs, but as mentioned it is too slow for my purposes. So if there was a way to allow for more output to be viewed in the Console at a time, or if someone has another solution to this issue, it would be appreciated. Thank you.

Hi Dahui,
It seems that you are trying to log an entire data frame; therefore, it is trimmed automatically. We recommend iterating the data frame or using the to_string() method to get the complete log. For issues with live trading, please get in touch with support@quantconnect.com with the live deployment attached.
Best,

It is a nice idea though Dahui, we'll explore trying to make it longer while balancing not crashing the web browser with huge text dumps.

Thank you both for the comments. However I am not trying to log an entire data frame, just print out one line for any ticker that passes some criteria each minute. I've attached a backtest (with a large amount of things removed from the original program, but should serve as an example still). After it starts running during market hours one of the first outputs should be:
where it can be seen part of the output is truncated to “…”.
Edit: The function that prints things out is enter(), which starts at line 335.
