Chart reading

How to read candlestick charts

Every crypto chart is built from candles. Once you can read one candle, you can read the whole chart.

Anatomy of a candle

Each candle shows four prices for one period of time:

  • Open — the first price of the period.
  • Close — the last price.
  • High and low — the extremes reached.

The thick body spans open to close. It's green (or white) when the close is above the open, red when below. The thin wicks show how far price travelled beyond the body before being pushed back.

Timeframes

A "1H" chart has one candle per hour; a "1D" chart one per day. Higher timeframes show the bigger trend; lower ones show detail and noise. A common habit is to check the trend on a higher timeframe and time the entry on a lower one.

Only closed candles count

A candle can look bullish halfway through the hour and close bearish. Signava only acts on closed candles for exactly this reason.

Patterns worth knowing

  • Long lower wick (hammer) — rejection of lower prices; buyers stepped in.
  • Long upper wick (shooting star) — rejection of higher prices.
  • Engulfing candle — a candle whose body completely covers the previous one, signalling a shift in control.
  • Doji — open and close almost equal; indecision.

Support, resistance and breakouts

When price repeatedly bounces from the same area, that's support; when it repeatedly fails at an area, that's resistance. A breakout is a close beyond one of these levels, and a retest is price returning to the broken level and holding — two of Signava's four spot setups are built on exactly this idea.

Don't ignore volume

A breakout on high volume is more trustworthy than one on thin volume. That's why every Signava spot signal requires above-normal volume on the coin.

Frequently asked questions

What timeframe is best for crypto trading?

It depends on how long you hold. Day traders use 5–15 minute charts, swing traders 1–4 hour charts. Signava's spot engine works on closed one-hour candles.

What does a long lower wick mean?

Sellers pushed the price down during the candle but buyers pushed it back up before it closed — often a sign of buying interest at that level.
