Reading candles

Every candle tells you four prices. Read them, and a chart stops being noise.

Step 1

One candle, four prices

Every candle covers one period of time and records four prices: open (the first price), close (the last), high and low. On a green candle the close is above the open, so the price ended higher. On a red one the close is below the open.

The thick part (the body) runs from open to close. The thin lines (the wicks) reach the highest and the lowest price.
Step 2

The body shows strength

Look at the size of the body. A long body means the price travelled far from open to close: one side pushed hard. A small body means a fight that nobody won, which often comes before a change.
  1. A long green body: buyers were in control the whole time.
  2. A tiny body: the price ended about where it started. Neither side won.
  3. A long red body: sellers were in control.

Step 3

The wicks show the fight

A wick is a price that was reached and then rejected. The longer the wick, the harder the push back. Long wicks at a support or resistance level from lesson 4 are some of the clearest signals a chart gives.
  1. Sellers pushed the price far down, then buyers pushed it all the way back. A long lower wick says buyers stepped in.
  2. Buyers pushed the price far up, then sellers pushed it back. A long upper wick says sellers stepped in.

Step 4

A timeframe is the size of a candle

The timeframe is how much time one candle covers: 5m is five minutes, 1h one hour, 4h four hours, 1d one day. Small candles join into big ones. Four 15 minute candles make exactly one 1 hour candle.

FOUR 15 MINUTE CANDLES

ONE 1 HOUR CANDLE

Same 60 minutes. The hour candle opens where the first quarter opened, closes where the last one closed, and reaches the highest and lowest of all four.
Step 5

Same market, different story

Because each timeframe shows a different amount of history, the same market can look like it is falling on one chart and rising on another. Neither is wrong. Always know which timeframe you are looking at, and check a bigger one before you decide. Lesson 5 turns this into a routine.

1 HOUR: FALLING

1 DAY: RISING

Same gold, same moment. The hour chart shows one bad day; the daily chart shows months of rising prices.
Step 6

Two prices, and the gap between them

A broker always quotes two prices: one to buy at and a slightly lower one to sell at. The gap is the spread, and it is a cost: buy and sell straight away and you lose it. It is usually small, but it widens at night and around big news. AiTradely shows one market price; your broker shows both.

SPREAD

BUY4,125.60
At a broker you buy at the higher price and sell at the lower one. The gap is the spread.

Watch out. A candle describes the past. A big green candle does not mean the next one will be green: it only tells you who was stronger while it formed.
