An automated trading bot for NinjaTrader 8 should be built around specific rules, not general trading intent. The platform can automate entries, exits, stops, targets, and management logic, but the behavior must be defined clearly.
What to define
Document the entry conditions, exit conditions, stop and target behavior, time filters, account handling, order types, and what should happen when the market disconnects or the strategy is disabled.
Testing path
Use historical testing, simulation, and monitored live review to confirm that the strategy behaves the way the written rules describe.
