Day trading involves opening and closing positions within the same trading day. It requires decisions about execution, position size and costs; a short holding period does not make a trade safe.
Understand the risk
Brazil’s CVM describes day trading as a high-risk activity. Leverage can increase exposure, and study does not guarantee consistent returns. Read the CVM educational booklet.
Record costs and assumptions
Before a simulation, record the instrument, position size, execution rules and relevant fees. Separate gross results from net results after costs. For derivatives, also examine margin and contract conditions; consult the CVM explanation of derivatives risks.
Use tools within their limits
Write down a maximum loss and the conditions for stopping a session before testing an entry sequence. The Dobrando Bancas calculator illustrates position arithmetic. It is not a market forecast, automated broker or live portfolio service.
