Day trading opens and closes trading positions within the same trading day or defined session. It describes the holding horizon, not a particular indicator, asset or guaranteed source of income. A day trader may make one trade or many, including very short scalps.
Define when the session ends
In markets with set trading hours, the approach normally avoids carrying the traded position beyond the chosen session. Crypto markets that trade around the clock have no single worldwide closing bell, so the strategy needs a stated timezone and session boundary. A chart's daily candle boundary does not automatically close a position.
Closing exposure before stepping away reduces the risk from holding that position during the absence. It does not undo losses already incurred or remove the possibility of sharp intraday moves.
Costs and controls remain
Repeated entry and exit can accumulate fees, spread costs and slippage. A perpetual position held across an applicable funding event may incur a funding payment even if it is opened and closed on the same day. Margin requirements can also apply throughout the session.
A workable plan specifies entry criteria, position size, exit conditions and when to stop trading. Account eligibility and securities day-trading rules vary by jurisdiction and provider; they should not be treated as universal crypto rules. Neither frequent activity nor ending the day flat establishes profitability.
