Data collection and backtest

Postby Wally_AD » 10 May 2014

I run a backtest some days with data from data IQFeed for one year.
In the Quote Manager "Collect RT Data" was set to ON.
Trying to run the same backtest in the Portfolio Backtester some days later without an internet connection did not work. The missing internet connection was the reason. I thougth data are collected in the database of the Quote manager and can be used later without other downloads.

What were your Data Download Mode settings in the Portfolio Backtester?

I guess "Download Data Before Backtesting" checkbox is activated. Can't check right now as MC is running on another machine.

The issue is then that if one day - the last day - is missing in the database the backtest is not started.
Correct, but without any hint not user friendly.

... the backtest is not started...
Do you mean there is an error message?

There is a window shown:
"Loading Data ... "

Instrument --- Status
@ES#C,IQFeed --- None

No error message. The program tries to load data and was waiting for ever for a connection.

The user has to cancel the backtest and change the data range, so that more data do not need to be downloaded.

This is not an issue.
I can't remember the problem I had two week before. So this topic can be closed.

Thank you Andrew.
