Moving average crossovers in NinjaTrader.

The general steps

Menu wording can differ between NinjaTrader 8 releases, so treat this as the outline and rely on a current walkthrough for exact clicks.

1. Open a chart of the instrument and timeframe you want, with enough history loaded for the longest average you plan to use. A 200-period average needs at least 200 bars of data before it can plot.
2. Open the Indicators window. Right-click the chart and choose Indicators, or use the indicators button on the chart toolbar.
3. Add the first average. Pick SMA or EMA from the list, set the Period (for example 21 for the slow line), and choose a colour and line width you can distinguish at a glance.
4. Add the second average. Add the same type again with the other period (for example 9), and give it a clearly different colour. Using the same type keeps the comparison clean.
5. Read the chart. A crossover is where the two plots swap places. Many traders colour the fast line warm and the slow line cool so the swap is obvious.

Calculate: on bar close or on each tick

An indicator can update every tick or only when a bar closes. On every tick, a crossover can appear mid-bar and vanish before the bar finishes. Looking at closed bars gives cleaner, though slightly later, signals. Check each indicator's Calculate setting so it matches the rule you are following.

Alerts and automation

You do not have to watch the screen for a cross. NinjaTrader supports condition-based alerts, for example through the Market Analyzer, and the platform's strategy tools can express rules such as one average crossing above another. NinjaTrader also includes sample strategies for learning how strategies are structured; these are educational examples, not recommendations. Before running any automated rule, test it on a simulator and read how to backtest it honestly.

Choosing what to plot

Before picking numbers, decide the timeframe you want to trade, and read about SMA versus EMA, the common EMA pairs and the best settings question. For long-term context, the 50/200 golden cross uses the same two-indicator setup on a daily chart.
