Start on the 4H.

Determine direction, mark key levels, and identify supply & demand zones.

Drop to the 1H.

Confirm the trend, look for breaks or reversals, and map Order Blocks, FVGs, and liquidity.

Only then move to the 15-minute chart.

This is where you wait for final confirmation before entering.

4H gives you the bias.

1H gives you the setup.

15-minute gives you the trigger.
