Alert Guard for NinjaTrader 8
Stop multiple orders. Trade once per setup.

Are your NinjaTrader alerts firing multiple orders when a condition stays true?
TradeGate solves this problem by acting as a gatekeeper for your alerts:

• ✅ One trade at a time – Blocks repeated order submissions while you’re already in a position.
• ✅ Automatic re-arm – Once your account is flat, the gate flips back to “FLAT” and your next alert is ready.
• ✅ Works with any strategy or indicator – Simply add TradeGate(Gate) == 1 to your Alert conditions.
• ✅ Visual status – A clear “FLAT / IN TRADE” label on your chart so you always know if new entries are allowed.
• ✅ Flexible setup – Supports Sim, Playback, and Live accounts. Choose your text color, font size, and background.

Why you need it
By default, NinjaTrader Alerts will keep firing as long as a condition is true, sometimes sending dozens of duplicate orders. TradeGate gives you protection against this, without needing to write code or run a full strategy.

Perfect for traders who use Alerts to auto-submit orders but want:

• One entry per signal
• No double-fills or spam orders
• Confidence that flattening resets the system cleanly
• includes free updates and support!
