There should really be an indicator or display of how many backtests compute units I have left on the account. Also, prior to running the backtest, each run should prompt and tell how many backtests will be consumed on the run. It wasn't exactly clear as I signed up for a demo account how many back test compute units a cloned algorithm was going to consume. This resulted in my single backtest blowing out the 500 backtests units during a single run consuming the entire account. The run didn't even finish with a result. It consumed the backtests and then disappeared. It would have been nice to see the result of at least 500 of the 2000. Now my account is pretty useless for the month because of an error I made in just trying explore the system and test things out.
