I agree with your opinion on more selling but we had a gap fill today and have reversed hard. I would have liked to see a retest of lows for a good double bottom pattern but maybe we do not get there. NVDA and AMAT and WSM reporting tonight. I like all these charts that you posted for potential reversals - great job picking those out. Strong finish into the close today (Nov 15) might be worth a morning gap swing but I will not touch these 3 that are reporting. Maybe an etf like TNA...will have to see how we close.

Yes margin does work on ETF's but the various brokers have different rules for the different ETF.s For example a short ETF will likely have a different margin rate compared to a long ETF. ie TNA versus TZA. Check with your broker on their rules.
