Category: Troubleshooting & Common Errors | Last Updated: April 2026

If your Vector strategy isn't taking trades, run through this short diagnostic before opening a ticket. In most cases the root cause is one of the first three items.

Quick Checklist

1. Is the strategy enabled? Go to Control Center → Strategies tab. Confirm the checkbox next to the strategy is checked. Strategies disable themselves on every NinjaTrader restart, and on broker disconnects — this is expected behavior.

2. Is your data feed live and flowing? Check the Connections window — the indicator must be green, and your chart candles should be updating in real time. A green connection with a frozen chart still means the feed isn't delivering data, and the strategy won't fire against stale ticks.

3. Is the correct account selected in the strategy properties? Right-click the chart → Strategies → verify the Account field shows the account you intend to trade. This is the single most common cause of "strategy isn't firing to the right account" when running across multiple prop firm accounts.

4. Have the strategy's signal conditions actually been met? Our strategies are selective by design — some sessions won't produce a trade at all, and that's normal. A strategy that's enabled, connected, and attached to the right account but hasn't fired may simply be waiting for its conditions to align.

Checking the Log for Errors

If you've gone through the checklist and still nothing is firing, check the NinjaTrader Log tab at the bottom of the Control Center for any red error messages.

The most common one you'll see is:

• "Strategy lost connection" — usually triggered by a broker-side disconnect during the session, or when a strategy was enabled on the day's fresh connection without refreshing it first. The fix is the same in both cases: refresh the connection (Connections → disconnect → reconnect) and re-enable the strategy cleanly. This is by far the most common log entry when a strategy stops firing.

If you see other error messages that aren't obvious, don't worry about interpreting them yourself — open a support ticket and our team will review them.

When to Open a Support Ticket

If you've run the checklist, the connection is green, the correct account is selected, and the strategy still won't fire on what you believe is a clear signal — open a support ticket with:

• Strategy name
• Instrument and timeframe
• Account used
• Approximate date/time of the expected trade

You don't need to send screenshots of the Log tab. However, in order to fully investigate, our team will need access to your VPS and NinjaTrader session. Looking at the log alone is often not enough to understand what actually happened — we need to see the chart state, the Connections window, the strategy properties, and the overall setup in real time. When you open the ticket, please be prepared to grant access so we can review everything end-to-end.

Bottom Line

Ninety percent of "strategy not trading" issues trace back to one of these: the strategy is disabled, the data feed isn't really live, or the wrong account is selected. Check those first. If all three look good and signals should have triggered, the strategy may just be waiting for its conditions — and if that's not it, open a support ticket and be ready to give our team access to your VPS so we can investigate the full setup.
