OHLC records the outcome, not every step of the path
OHLC stands for open, high, low and close. For an ordinary time-based candlestick, the open and close provide the beginning and ending prices for the period, while the high and low describe its recorded price range. These four prices compress a period of market activity into a useful chart symbol, but important details are lost.
A single candlestick generally cannot tell us exactly when the high and low occurred, how many times the same price was crossed or how many executable quotes were available at those moments. Interpreting candlestick patterns is an analytical method, not a tick-by-tick record of events.
To understand shadows, first see Does a Long Upper Shadow Always Signal a Market Top? Understanding the Battle Between Buyers and Sellers. Here the question goes further: after seeing a shadow, what parts of the price path remain unknown?
A bullish candle can still close below the previous candle
Consider a hypothetical example. The previous candle closed at 2325, while the current candle opened at 2300 and closed at 2308.
The current close is 8 dollars above its own open, so this is a bullish candle. Yet it is also 17 dollars below the previous close. Both comparisons are correct because they use different reference points. Describing the candle as bullish is not the same as saying gold rose compared with the preceding period.
Some platforms color candles according to the current open-to-close relationship, while other display settings may use the comparison with the preceding close. Always check the chart settings and values rather than relying on color alone to assess price changes or trends.
A long shadow cannot identify who was trading
A long lower shadow indicates that quotations below the lower edge of the candle body occurred during the period. OHLC alone cannot tell us which participants bought, whether large institutional orders were involved or which event triggered the subsequent move.
When the intrabar sequence is unknown, a claim such as “institutions first dumped gold and major players then pushed it higher” introduces identities and events that the chart does not establish. We may describe the observed price range and closing position or suggest an explanation for further testing, but those are different kinds of statements.
The trend context remains useful, yet it cannot restore missing tick-by-tick history. For more on the relationship between patterns and trends, see Why the Same Candlestick Pattern Can Mean Different Things at Different Trend Stages.
To establish the order of the high and low, examine shorter intervals
If the hourly high appears within an earlier five-minute candle and the hourly low appears within a later five-minute candle, those finer records can help establish their order. However, if both extremes occur within the same five-minute candle, the uncertainty has merely been narrowed to that five-minute period.
Moving to shorter intervals or examining time-stamped tick records may provide additional detail, provided those records actually exist and cover the relevant interval. Before comparing sources, confirm the instrument, quotation provider, time zone and candle boundaries. Data from another platform should not automatically be treated as the exact path represented by the current chart.
A sound review should distinguish what the original candle confirms, what finer data establish and what remains unknown. Missing observations should remain unresolved rather than being replaced with a plausible story.
Touching a stop and a target does not establish the execution outcome
If a candle's range includes both a stop-loss level and a profit target, deciding which came first also requires information about when the position was opened, when the orders became active, the prices used to trigger them and the sequence of price observations. If a trade entered halfway through the period, a high reached before entry cannot be treated as an available profit.
Even a verified sequence of price touches does not guarantee that an order would have executed at those exact prices. Order type, bid-ask spread, slippage and market liquidity also matter. See What Is Liquidity? Why Is Gold Sometimes Easy to Trade While Spreads Suddenly Widen?.
Backtesting tools sometimes impose simulated rules when the intrabar sequence is missing. For example, TradingView's strategy documentation explains that its default broker emulator infers a path within historical candles from OHLC values, while lower-timeframe data can provide additional detail. These are simulation assumptions, not evidence that the original candle recorded the true sequence, and the same rules should not automatically be applied to other platforms.
How can chart conclusions stay within the evidence?
For the hypothetical candle, a defensible description would be: “The close was above the open, the recorded price range was 2285 to 2330, and the order of the high and low has not been verified.” This statement separates what is known from what remains uncertain.
If complete finer records later become available, the sequence and timing can be added. Forecasting the next period requires examining consecutive candles and their position within the wider price structure, rather than treating a guessed intrabar path as a prediction. See Are Three Consecutive Candlesticks More Reliable Than a Single Candle?.
A single candlestick summarises a price range and the relationship between its open and close. Questions involving intrabar order, execution timing or trading outcomes require the relevant underlying records.
