Bit of a hiccup back in April. Renko now indicating to stay long.
Renko chart says, stay long. I believe when you see 2 or 3 consecutive same colored candles you either stay long (green) or stay short (red)
The ol' bollinger bands have been pretty reliable so far YTD for SPY...
Still got room to run??? Looking at this chart you could make an argument for it....
