Why do I use hollow candles & not traditional Japanese candlesticks? Are hollow candles just a cosmetic change, or do they provide us with some extra information that a traditional candlestick doesn’t?

A thread 🧵:

Traditional Japanese candlesticks are all solid. They are either green or red (colors may vary, but you get the point).

Hollow candles use two attributes to provide information regarding the price:
- Color of the candle
- Whether the body of the candle is filled or not

So, a green hollow candle can have its close > open (just like traditional candlesticks), or its open > close (here its body will be filled). Similarly, a red hollow candle can have its open > close (traditional), or its close > open (here its body will be hollow).

The colour of a hollow candle is decided by comparing the closing price of the current candle with that of the previous candle. So, a red-color candle (irrespective of whether it’s filled or not) means that the current candle’s close is lower than the previous candle’s close.
