Strategy execution
NinjaTrader Calculate modes: bar close, each tick or price change
Calculate controls when bar logic runs. See what changes between bar-close, tick and price-change processing, and why historical data needs separate attention.
Order management
NinjaTrader Time in Force: DAY, GTC and GTD order expiry
An order's expiry setting and a strategy's session-close behavior are different. Learn the DAY, GTC and GTD rules, including locally simulated GTD.
Strategy data
NinjaTrader bars required to trade: when a strategy needs more data
Enabled does not mean every data series has enough history. Check the bar threshold, CurrentBars indexes and the separate startup state.
Order management
NinjaTrader stop-market vs stop-limit: why a stop may not fill
A stop price activates an order; it does not confirm a fill. Compare the two stop types, limit offsets, and locally simulated triggers.
Order management
NinjaTrader OCO orders: why linked orders cancel together
An OCO group links order outcomes. Learn why cancelling one order can remove another, when IDs reset, and what changes after a disconnection.
Windows reliability
NinjaTrader and Windows sleep: what stops monitoring
A dark monitor can leave NinjaTrader running. A sleeping computer cannot keep executing its desktop strategy logic. Check the power state behind the gap.
Strategy automation
NinjaTrader ATM vs NinjaScript strategies: who manages the orders?
An ATM manages a trade's exits; a NinjaScript strategy can generate its signals. Combining them changes how you track orders, positions and results.
Simulation and testing
NinjaTrader Playback vs Sim101: what each test actually measures
Choose the right data and simulation account, understand why fills differ, and save your replay results before a reset.
Platform diagnostics
NinjaTrader diagnostic logs: collect log and trace files for support
Find the diagnostic files support needs, collect them after a crash, and distinguish a Log-tab export from the full log and trace package.
NinjaTrader repair
NinjaTrader backup and restore: preserve the right files before repair
A workspace export preserves layouts; a backup archive can preserve configuration, trade history, scripts and diagnostics. Select what matters before repair, then verify what returns.
Trading hours and sessions
NinjaTrader trading hours: templates, time zones and missing bars
A session filter can look like downtime. Compare the clocks, holiday exceptions and data series before treating the gap as a connection failure.
Futures contract rollover
NinjaTrader futures rollover: update contracts and automated strategies
Changing a chart contract does not finish an automated-strategy rollover. Separate workspace changes, strategy settings, live positions and historical data.
