The problem, in detail
When NinjaTrader 8 slows down or freezes the candles, it's not bad luck
With use, the NinjaTrader 8 database grows and can get damaged. The result: the platform is slow to open, the candles stop and, at the worst moment, it freezes. And a freeze with open positions is not a technical detail: it means losing control of your risk.
What's at stake
A single freeze at the wrong moment costs more than a year of protection
A freeze with an open position can cost you a whole trade — or the account. And it gives no warning: it happens at the worst moment.
$0.27 a day to keep NinjaTrader healthy. It costs you less than the commission on a single trade — and the first one it prevents has already paid for it.

Frequently asked questions
What people ask before buying
Do I need to know about databases?
No. TSD DB Guardian works on its own, in the background. You trade; it watches, backs up and repairs.
Is it a NinjaTrader indicator?
No. It is an external Windows program that lives alongside NinjaTrader 8 and looks after it from outside; that is why it stays active even if the platform freezes.
Can it delete or damage my data?
No. Before repairing it makes an encrypted and verified backup. If something is off, your data is safe.
And if NinjaTrader is already frozen?
You use the panic button: it closes, cleans, repairs and verifies the database before reopening the platform.
How do I try it and how do I buy?
You start with the full 14-day demo, no card. If you like it, the license is $99/year. The demo expires on its own, no automatic charges.
