Basic trading with FiveTwenty

These lessons explain how to read OANDA data, distinguish trades from positions, and keep decision logic separate from account operations. They build on authentication and the practice trade lifecycle.

Lesson	What you will do
Model and numeric basics	Use typed response values and instrument metadata
Market data	Read quotes and completed candles
Position management	Inspect exposure and close a specific trade
Strategy building	Write and test a signal calculation without submitting orders
Assembling a workflow	Connect reads, calculations and a decision preview

The examples assume Python 3.10 or later and a configured practice account. A helper function is intended to be called inside an existing client context; blocks with asyncio.run(main()) are complete scripts. Each lesson states whether its example changes account state.

These are SDK lessons, not validated trading strategies. A successful API call or a working signal calculation does not establish profitability. For order behavior, continue with advanced orders; for limits of sizing calculations and protective orders, read risk management.
