Placing a trade
To open: set your volume (lots), add your stop loss and take profit, then Buy or Sell (market) — or place a pending order at a chosen price.
To manage: you can move your SL to breakeven once in profit, take partial profits at TP1, and trail your stop. Never remove a stop loss to "give it room" — that's how accounts blow up.
Tip: always set SL/TP when you open. Deciding under pressure leads to emotional mistakes.
