Potential Short on BTC

Based on my current S/R lines and the Whales Buy-Sell indicator combined with the MFI Pro, it looks like BTC may be headed for a short-term retracement. My Whales Buy-Sell indicator has been fairly accurate on the 8hr timeframe for BTC when combined with the MFI Pro (as seen above, it called the bull run), and it just now flashed a Sell signal. My MFI Pro indicator also crossed the white signal line to the downside, indicating a stronger possibility of a retracement. My first target for the BTC retracement is the $57,853 support level. After that, I'm looking at $54,180, then $50,918.

Let me know if you have any questions on the indicators mentioned or any of the TA I posted :)
