database image is malformed

[vesipeto]

Hi

While I was trying to code Addon for risk management that closes trades that are too much in loss I managed to get ninjatrader to a state that it didn't respond multiple times and now I get error database image is malformed when I try to reset the sim101 account. Do I need to reinstall ninjatrader or?

cheers

Hello,
Thank you for your post.

Please note, when resetting your database file the following will be lost:

• Trading Hours templates, Instrument Lists / Custom Instruments, historical trade execution data, saved Strategy Analyzer backtest results

To prevent running into situations where you can potentially lose important data, we advise running regular backups via our inbuilt backup feature in NinjaTrader:
