In my opinion Stellar is currently in wave 4 of the Elliott wave principle.
Wave 4 is typically moving sideways for some time, which it did. It often retraced to 38,2% or less of the 3rd wave.
Wave 5 is often smaller than wave 3 and similar to wave 1.
As shown, if wave 1 = wave 5, Stellar will be going back to previous highs, hitting resistance again at around the 830-850 level.
