Ichimoku Breakout With Confirmation (BCW) Question

This should do the trick. Try it out and let me know. Screenshot below shows the scan results on a chart. The last two lines are your signals. I have commented out the last one (Chikou cross below cloud) so that you can copy and paste this directly into a study filter of a scan without creating an error. Just move the comment mark depending which signal you want the scan to pick up.

declare lower;
input tenkan_period = 9;
input kijun_period = 26;
def Tenkan = (Highest(high, tenkan_period) + Lowest(low, tenkan_period)) / 2;
def Kijun = (Highest(high, kijun_period) + Lowest(low, kijun_period)) / 2;
def spanA = (Tenkan[kijun_period] + Kijun[kijun_period]) / 2;
def spanB = (Highest(high[kijun_period], 2 * kijun_period) + Lowest(low[kijun_period], 2 * kijun_period)) / 2;
def Chikou = close[-kijun_period];
def chikouAboveClound = Chikou[kijun_period] > spanA[kijun_period] and Chikou[kijun_period] > spanB[kijun_period];
def chikouBelowCloud = Chikou[kijun_period] < spanA[kijun_period] and Chikou[kijun_period] < spanB[kijun_period];
plot chikouCrossAbove = !chikouAboveClound[1] and chikouAboveClound;
#plot chikouCrossBelow = !chikouBelowCloud and chikouBelowCloud;
