Some people doesn’t even know what a candle mean.
Yup, i bet you don’t know how a candle is being formed, what makes a candle green and what makes it red?
The answer is as simple as the question itself, the amount of buyers and sellers.
Simply, candles were invented to measure the market of an asset, how an asset is performing, and it’s tool to do so is the candle.
When buyers are more than sellers, the candle will be green which indicates interest in buying the asset at the current price.
And if buyers are less than sellers, then duh! The candle will be red which indicates a loss of interest in the asset at the current price.
