Library & Frameworks
The ChartJS library provides modules for creating candlestick charts. It also supports generating OHLC (Open High Low Close) charts. Let’s add some customization to our candlestick chart by setting up a custom date range picker and selector. With this feature, users can easily navigate date/time-based charts and select specific periods for further analysis.
It shows equilibrium — buyers and sellers in a standoff. Indecision patterns warn traders that neither side is firmly in control. Continuation patterns help traders recognize when a trend is consolidating rather than reversing — valuable insight for managing open positions. These bearish patterns are most effective when they form at resistance or after long rallies, ideally alongside declining momentum or RSI divergence.
After a strong uptrend, it starts with a big bullish candle, then an indecision candle, and finally a large bearish candle that closes well into the first. This pattern often appears at the top of overextended rallies. Another classic is the Morning Star, a three-candle pattern.
Alright, it’s time to put all the pieces together and create our awesome candlestick chart for TSMC! Let’s start by writing some JS code to make our chart functional.

Many beginners misuse candlestick patterns by taking every signal as a trade. Avoid trading patterns in low-volume markets or against strong trends. A bearish reversal on a powerful bull run often leads to frustration, not profits. Finally, the Dark Cloud Cover pattern warns of an incoming storm. It begins with a green candle and follows with a red candle that opens higher but closes below the midpoint of the first — a sudden flip in sentiment. A green (or white) candle means price closed higher than it opened — buyers dominated.

The price range is the distance between the top of the upper shadow and the bottom of the lower shadow moved through during the time frame of the candlestick. The range is calculated by subtracting the low price from the high price. The area between the open and the close is called the real body, price excursions above and below the real body are shadows (also called wicks). Wicks illustrate the highest and lowest traded prices of an asset during the time interval represented.
