In the previous course, we simply learned about the shape analysis of candle diagram. Now, we will go deeper and discuss more details. Let's start now.
What is candle trading?
When our animated character Godzilla was a cute little lizard, the Japanese had created an ancient version of the technical analysis method they used to trade rice. Yes, it's the way to trade rice.
A westerner named Steve Nison "discovered" the technical secret of "Japanese candle map" and learned this unique trading technology from many Japanese brokers. Since then, Nissen has made an indissoluble bond with the Japanese candle map. He studies this unique technology day and night, and begins to write related books. Slowly, this mysterious method of technical analysis became popular in the 1990s. To make a long story short, without Steve Nissen, the Japanese candle map might still be a secret.
So, what is the foreign exchange candle chart?
The best way to explain it is to use graphics:

Candle line can be divided into different periods of time for use, whether it is a day, an hour, 30 minutes, is not a problem. Candle chart is used to describe the price fluctuation in a specific period of time.
The candle line is composed of opening price, closing price, highest price and lowest price within a certain period of time.
If the closing price is higher than the opening price, we call the candle line the negative line;
If the closing price is lower than the opening price, we call the candle line positive;
The hollow part of the candle line is called "entity";
The thin lines on the upper and lower parts of the candle are called shadow lines;
The top of the upper shadow line is the "highest point";
The bottom of the lower shadow line is the lowest point.
