Education is context, not advice
These pages explain common market and platform concepts in general terms. They do not take account of personal circumstances, financial position, experience, or objectives, and they do not recommend a trade, instrument, strategy, or position size.
A practical order for learning
Understand bid and ask pricing, notional exposure, margin, and the difference between an order, deal, and position. Then study instrument specifications, trading sessions, cost, and risk controls. A platform function should be understood before it is used with leveraged exposure.
