Trading mechanics
Spread, commission, financing, margin, contract size, execution, and market hours all contribute to the risk and cost of a trade.
The visible market price does not by itself show the full exposure of a leveraged position. Position volume, contract size, account currency, margin requirement, spread, commission where applicable, and overnight financing can all affect the cash impact and risk of a trade.
MetaTrader 5 exposes symbol-level information from the trading server. Use it to check volume limits, contract size, tick size, currencies, swap fields, and sessions. The documents associated with the relevant account remain the source for account-level terms and charges.
