How candles work ?

[Greg L.]

Hello folks,

Gekko stores one-minute candle in database, but I was wondering how it works for x-minute candles.
For example, if I want to get data on 15 minute candles, what records do I need ?
Is opening price at x and close price at x+15 minutes ?

Thanks !

You only need to change the candle size from 1 to "X".

Yes, Gekko will automatically calculate the candles you want on the fly. The good thing about candles is that it's easy to "calculate" 15min candles by taking 15 one minute candles.
