This is the one hour tunnel method im working on
study(title="EMA 1h Tunnel Detector", shorttitle="EMA CROSS SIGNAL", overlay=true) ema1_len=144 ema2_len=169 ema3_len=16 out1 = ema(close, ema1_len) out2 = ema(close, ema2_len) out3 = ema(close, ema3_len) out = cross(out1, out3) outb = cross(out2, out3) outc = cross(close,out3) plot((out2 - 0.0015), title="sell signal", color=orange) plot((out1 + 0.0015), title="buy signal", color=blue) plot(out2, title="ema169", color=red) plot(out1, title="ema144", color=green) plot(out3, title="ema12", color=yellow) plot(out ? out1 : na, linewidth=4, style=cross, color=lime) plot(outb ? out2 : na, linewidth=4, style=cross, color=red) plot(outc ? out3 : na, linewidth=4, style=cross, color=blue)
