Cortex AI Strategy for NinjaTrader 8 — CORTEX decides, the strategy manages the position
ES (E-mini S&P 500) · Entries from CORTEX · Confidence control · Direct brackets
Managing orders by hand can hurt your trading results
You spot the setup. You enter. Then the stress begins: move the stop, take a partial, let the runner go. Several decisions per trade — all under time pressure.
Entries on gut feeling
A signal looks good — but is the order book pushing the same way right now? Is the market asleep? Did you already enter five minutes ago? Nobody checks that reliably second by second.
Stops moved too early or too late
Breakeven by feel, partial forgotten, runner closed too early or left running too long. Management often decides more about the result than the entry.
No learning loop
Tomorrow you sit at the chart again and take the same setup. Without a model that learns from your data, you repeat your patterns — the bad ones too.
Three protection layers between your capital and a bad trade
The Cortex AI Strategy is developed, tested and optimized exclusively for the ES (E-mini S&P 500). The stop/target distances and order-flow thresholds are tuned to the volatility, tick structure and liquidity of the ES — on other instruments such as the NQ the same settings can lead to instant stop-outs, so we make no claim of functionality there.
CORTEX decides whether and in which direction to enter. Fixed gates check the moment. The strategy manages the position until the exit. Every layer is visible on the chart and in the app’s strategy panel.
CORTEX decides the entry
The direction comes exclusively from CORTEX in the desktop app — the strategy has no direction logic of its own. An entry needs a minimum confidence, and you set it yourself.
- Long or short only from the CORTEX signal
- “CORTEX Min Confidence %” control: 65–95 %, starting value 75 %
- Higher gate = fewer, more selective entries
- No entry without the app running
Fixed gates before every entry
Before an order goes out, the strategy checks the moment. If a gate fails, it stays out — it does not enter only to rescue the trade later.
- Order book fresh and weighted in the CORTEX direction
- Quiet phases and a neutral book are skipped
- Minimum spacing between two entries and a daily limit
- Open guard: no entries in the first 15 minutes after the session opens
- No entry chasing a move that just ran
The strategy manages the position
Entry, stop and two targets go to NinjaTrader as direct orders — no ATM template. After the first partial the rest runs as a runner and the stop moves to breakeven.
- Direct bracket orders: stop, T1, T2
- Default 2 contracts: one takes T1, one runs as the runner
- Trade manager: trail the stop, breakeven, early exit
- In the NinjaTrader chart panel: pause, long only / short only, flat, breakeven
How a trade runs — from signal to learning step
Schematic flow of a Cortex AI Strategy trade. The values in the picture are examples, not a trading recommendation.
Six steps, none of them by hand
You decide beforehand how strict CORTEX has to be. After that, entry, protection and exit run without intervention — you can pause or close the position at any time.
- CORTEX SIGNALCORTEX reports a direction with confidence above your gate.
- GATESOrder book, market phase, spacing to the last entry and open guard are checked.
- ENTRY + BRACKETEntry, stop and two targets go straight to NinjaTrader.
- T1The first contract takes profit, the second keeps running.
- RUNNERIf the trade keeps going, the runner’s stop moves to breakeven.
- EXIT + LEARNINGExit via T2, stop or trade manager. The trade goes into CORTEX’s learning data.

Frequently asked questions about the Cortex AI Strategy
The six questions traders ask most before they let the strategy run.
Who decides whether the strategy enters?
CORTEX, the neural engine in the desktop app. It provides direction and confidence. The strategy has no direction logic of its own: without a CORTEX signal there is no entry, and the desktop app has to be running.
After that the strategy only checks whether the moment fits (order book, market phase, spacing to the last entry, open guard) and manages the position.
What does the confidence control set?
In the NinjaTrader strategy dialog it is called “CORTEX Min Confidence %”. It sets how certain CORTEX has to be before the strategy enters: from 65 to 95 %, starting value 75 %.
A higher gate means fewer but more selective entries; a lower one means more entries. You find the value that fits your trading yourself — ideally in a sim account first.
Does the strategy learn from a pretrained model?
No. There is no pretrained model. CORTEX starts from zero and learns from your own feed and the strategy’s trades.
You see every real training step in the app’s strategy panel, in the CORTEX LEARNING tile.
How are stop and targets set?
Entry, stop and two targets go to NinjaTrader as direct orders — no ATM template. With the default size of 2 contracts, one takes the first profit (T1) and the second keeps running as the runner; its stop moves to breakeven.
A trade manager can trail the stop, move it to breakeven or close the position early. In the strategy panel on the NinjaTrader chart you can pause at any time, trade long only or short only, move the stop to breakeven or close the position.
Which instruments does the strategy run on?
The Cortex AI Strategy is developed, tested and tuned exclusively for the ES (E-mini S&P 500). Stop and target distances and the order-flow thresholds are matched to the ES’s volatility, tick structure and liquidity.
We make no functional claim for other instruments.
Which plan do I need?
The Cortex AI Strategy is included in Pro and Ultra; Ultra adds MBO (market by order) via Rithmic. Trial, Basic and Plus do not include the strategy.
For live trading you also need a NinjaTrader 8 license and a Level 2 data feed. Current prices are on the pricing page.
