A candlestick is the most common unit of information in retail forex trading. Entire methodologies have been built around reading candles, their shapes, their relationships to each other, their position relative to support and resistance levels. But understanding precisely what a candle communicates, and equally importantly, what it cannot, is essential context for understanding why quantitative pre-session forecasting operates on a different and complementary level.
What a Candle Actually Contains
A candlestick contains four pieces of information for a defined period: the open price, the high price, the low price, and the close price. For a daily candle, these four values represent the net result of every order that was executed in the forex market during that trading day. That is what a candle is: a compressed record of a completed period.
A candle can only tell you what already happened. It is a historical record. The moment a daily candle closes, the information it contains is already in the past. When you read it, the market has already moved on to the next period.
What a Candle Does Not Contain
A candlestick does not contain information about the order flow that created it. You can see that price reached a high of 1.0912 and a low of 1.0788 during a session, but the candle does not show you whether the high was reached because of a large institutional buy order, a stop-hunt, or a macro news reaction. The mechanism is invisible in the candle record.
A candle also does not contain information about what will happen in the next period. Pattern-based analysis, identifying doji candles, engulfing patterns, hammer formations, is an attempt to infer forward-looking probability from the shape of completed candles. These inferences have some statistical basis in aggregate, but they are probabilistic at best and subject to significant variance at the single-candle level.
Interpretation vs. Forecasting
There is a meaningful difference between interpreting a candle and forecasting the next one. Interpretation is the skill of reading what price has done and constructing a narrative about what it might mean. Forecasting is the attempt to calculate what price is probable to do based on the statistical properties of how price has moved historically.
Both are legitimate activities. But they have different error rates, different data requirements, and different applications. Chart interpretation is faster and more flexible, it can incorporate visual context that a model might miss. Statistical forecasting is slower and more rigid, but it does not suffer from the cognitive biases, anchoring, recency bias, confirmation bias, that affect human pattern recognition under pressure.
Where Candles Fit in a Quantitative Approach
Quantitative range forecasting does not replace candle reading. It operates before the candle forms, providing a statistical framework for the session that is about to happen. Once that session is underway and candles are forming, the trader's real-time interpretation of price action within the forecast range is a separate and complementary discipline.
The most effective integration uses the pre-session forecast to define the probable range, and the trader's own candle analysis to determine entry timing within that range. The forecast says where the boundaries probably are. The candles developing within the session help determine when and where an entry is appropriate within those boundaries.
The key insight is simple: a candle is excellent data about what has already happened. A quantitative forecast is statistical data about what is probable to happen next. Used together, they provide more complete information than either provides alone.
