SPY(4h) - 4 hr RSI chart short signal

I've posted this indicator alert few times before, for the past 2+ years a 4 hour RSI overbought has been a good indication of short term market top. Failed once as pointed out on the chart. We are at the channel high but the MM target is still a little higher so maybe a day or two before we see a turn lower. Lets see if the signal works again
