Using HA bars --smoothed or not-- is one way to filter a bit of the noise from a time-prices series. Moving from daily bars to weekly bars achieves the same goal. If HA bars don’t please your eyes, try other charting formats such as Renko, Three Line Break, or the old classic of Point & Figure.
But no matter which charting format you choose, which time-frame, or which indicators, keep in mind this Buddhist proverb: “A way of seeing is also a way of not seeing.”
