RSI Scanner bug?

Hi Pete,

Please take a look at the code below and attached images. I notices that there’re times the scanner is not working correctly (I set it to scan on 15 mins.). RSI is below the centerline (50), but it alerts as above 50. Any bug? Please advise.

input length = 14;
input price = close;
input averageType = AverageType.WILDERS;
def rsi = RSI(length, 70, 30, price, averageType).RSI;
def centerLine = 50;
# use this to scan for rsi crossing above the center line
plot scan = rsi[1] < centerLine and rsi > centerLine;
# use this to scan for rsi crossing below the center line
#plot scan = rsi[1] > centerLine and rsi < centerLine;

input length = 14;
input price = close;
input averageType = AverageType.WILDERS;
def rsi = RSI(length, 70, 30, price, averageType).RSI;
def centerLine = 50;
# use this to scan for rsi crossing above the center line
#plot scan = rsi[1] < centerLine and rsi > centerLine;
# use this to scan for rsi crossing below the center line
plot scan = rsi[1] > centerLine and rsi < centerLine;
