Scan For Price Drops

[shellyonthepelli]

Scan for a drop of a certain amount in price down from 5 bars ago

I'm trying to get this scan to alert when price drops, any suggestion on why this doesn't work?

input length = 1;
input price = OHLC4;
input averageType = AverageType.SIMPLE;

def avg = MovingAverage(averageType,price,length);
def height = avg - avg[5];



plot scan = height < -.55 ;

Try this. Hope helps

input price = OHlc4;
input length = 1; 
input dropAmount = 0.55;

# Calculate the price drop
def drop = price[length] - price;

plot scan = drop >= dropAmount;
