Scan for stocks that have spiked at least once in the past

Hello Pete,

So below I have provided the code for a chart label that counts the amount of time a stock has spiked in the past (aka a former runner). My question is, how can we turn this into scan criteria. When using this scanner, I only want to return stocks that have spiked at least 1 day in the past on the daily chart in the within past 2 years. This code works well as a label, now let’s see if we can create a scan.

input percentSpike = 40.0;

input countLimit = 5;

def percentRise = 100 * (high / open – 1);

def condition = percentRise >= percentSpike and volume > 5000000;

rec counter = if condition and BarNumber() >= 0 then counter[1] + 1 else counter[1];

*Bonus, this will be even cooler if we can add a slider (optional)
