Alternative alert setup for RSI daily study

Hi Pete, I tried to setup a RSI daily study and managed to plot the study after reading one of your older post. However that didn’t work for alert as there are recursive references. Is there any alternative of having the alert setup for RSI daily?

My code below:

input length = 14;
input overBought = 70;
input overSold = 30;
input averageType = AverageType.WILDERS;

def NetChgAvg = MovingAverage(averageType, close(period = AggregationPeriod.DAY) – close(period = AggregationPeriod.DAY)[1], length);
def TotChgAvg = MovingAverage(averageType, AbsValue(close(period = AggregationPeriod.DAY) – close(period = AggregationPeriod.DAY)[1]), length);
def ChgRatio = if TotChgAvg != 0 then NetChgAvg / TotChgAvg else 0;

def RSI = 50 * (ChgRatio + 1);

## The RSICross is meant to signal only 1 as Oversold and stay there until the next signal 0 as overbought, vice versa. So I only receive signal when there is a change of signal.

def RSICross = if RSI crosses above overSold then 1 else if RSI crosses below overBought then 0 else RSICross from 1 bar ago;
plot Scan = RSICross;
