The lookback will depend on the Indicator you are using. For example, if you are using an SMA with a length of 20 candles, you will need 20 candles of warm-up. if you are using 30min candles that would be 10hrs so 1 day is plenty. If you are using 12-hour candles you would need 10 days. And so on.

Here's 2 examples of a DMA (35 candles) plot on 1H candles in the same period.

### Using 10 days lookback:

### Using 1 day lookback:

We try to auto-update the Lookback value based on the candle you selected, but users should always check to make sure it fits their strategies.
