A candle tells you four things
Speak the market's language: exchange, candle, long/short, leverage, and costs — without this, the rest of the program reads like spellcasting.
Step 1 · What's in a candle
A candle records four prices.
BTC 4h, Jul 21, 2024, the 16:00 candle: where price opened, how far it went up and down, and where it closed four hours later.

The body tells you who won.

One 4h candle holds 16 15m candles.
The same 16:00 candle on 15m. The whole flush fit into two candles, 17:45 and 18:00: the 4h shows the result, the 15m shows how price got there.
