Day Trading is a time structure for trading, not an independent source of returns. A strategy must specify when an entry may arise, how it is executed, when it ends and how an unclosed position is monitored. Profit is measured from executed trades after costs, not from the difference between the day's lowest and highest prices.
Day Trading means opening and closing trades within a chosen trading day or session. Fidelity describes intraday trading as short-term trades usually within one day and highlights its demands on time and its risks. The name alone specifies neither entry, direction, trade count nor expected return; the rule must be concrete for Bitcoin too. [1]
Record the exchange, instrument, timezone, session start and end, and the time after which no new positions should be opened. A daily candle aggregates data; it does not automatically end market availability. Crypto can trade outside traditional exchange hours, but availability and technical breaks differ by product; Coinbase, for example, lists maintenance even for futures offered on a continuous basis. Exiting before the day boundary must therefore be a separate executable rule. [2]
A specific rule may use a breakout, continuation or reversion to a reference. A short horizon alone does not unify those methods. Specify the data, signal completion, position size, invalidation, target and time-based exit. If a signal appears too close to session end, the rule must determine whether an entry may still be submitted; this cannot be chosen afterwards according to the result. [1] [7]
Distinguish completion of the calculation, order submission and actual fill. TradingView's default model fills a market order no earlier than the next available tick, often at the following Open; simulation settings must be explicit. CME Group notes that a limit order may remain unfilled and a stop may not execute at exactly the specified price. Over a short horizon, execution differences can materially change the result. [3] [4]
A candle containing both entry and exit levels does not prove that both could have been traded in sequence. TradingView uses intrabar movement assumptions when detailed data is missing; finer data can change simulated fills. If a stop and target occur within the same candle, their timing and liquidity must be addressed. The day's High and Low are not automatic purchase and sale prices. [3]
Results include actual entry and exit fills, position size, spread, fees and financing where applicable. FINRA warns that frequent trading costs can reduce returns. Their share can be substantial for a small price move. Do not deduct the same spread or slippage twice if it is already included in the stated fill prices; conversely, do not omit it when a test uses only a reference price. [5] [3]
Predefine a position-size limit, a rule to stop further entries after losses and a response to connection or exchange outages. Submitting an exit order is not proof that a position is closed; monitor its status and remaining active orders. Leverage can amplify losses even over a short horizon, and liquidation may precede the planned exit. A stop does not guarantee an exact loss boundary; spot purchases and derivatives have different conditions. [6] [4]
Keep records of all signals, orders, fills, costs and open exposure at session end, including unsuccessful days and unfilled trades. Parameters must not be selected using future data. CFA Institute highlights look-ahead bias, structural breaks and out-of-sample evaluation. The trading style must also be distinguished from specific account, margin and jurisdiction rules; one market's rules cannot automatically be applied to every Bitcoin product. [7] [5]
Gross movement and costs of one intraday trade

01Does Bitcoin have one universal end of the trading day?+
Not across all products and platforms. A strategy must define its own timezone and session boundary while respecting that market's availability. The end of a daily candle does not itself close a position or cancel active orders.
02Does a positive difference between purchase and sale prices mean net profit?+
Not automatically. Quantity, actual fills and costs on both sides, including any financing, must be known. Even a positive gross result can shrink or turn into a loss after costs; taxes and other obligations are a separate matter.
