Looking at Solana on a 1W time frame:
I've added the Fib Extensions and Retracements from the Maximum low and high, they are in my opinion the ones that matter most.
I also included the Bull Market Support Band derived from BTC, which would indicate it could come into effect near where the wave 4 retracement could interact in a support way for more confluence near the channel boundary, also giving us a time estimate of when it will arrive there in a few more weeks...
BMSB = 21w SMA & 20w EMA
Further confluence with BTC which could be doing a similar move down to it's BMSB
