ATR + Volume Spikes For ThinkOrSwim

[antwerks]

I loaded this script into my scanner for both a buy and sell on the S&P 100 yesterday and I didn't get any signals. Did you try this on Friday by chance? Many thanks.

I hit on 2 with the 15 minute scan lol... FWRG and SRE

Zooming out to a daily scan I hit on 50 - hour scan hit on 6 and 30 minute hit on 4

This is an example of a stock in 3 of th e4 returned hits

Can an alert be set up to notify the user when price action crosses the VWMA line or the candles turn from red to green or green to red?

I dont know what I am doing wrong. I copied and set up a new scan for a buy and then a sell and nothing came up today for the S&P500 on both a 15 min and daily. Ideas? Thanks

I still don't see anything show up. have attached the script I used for the scan, and two of the scan boxes. Any ideas are appreciated.

I still get nothing. Here is the script I used . I modified the last two lines for a buy or sell. The other two photos show screens for setting up the scan. I made the % up and down much larger than normal to see if that made a difference. Many thanks for your suggestions.

I am afraid that I am old and can not see the images clearly. here is the code I am using. Not sure if the little changes you have made make that big of a difference. It is a tight code in terms of very specific stocks.

# SCANNER SCRIPT ONLY

input atrPeriod = 20;
input atrMultiplier = 4.0;

def atr = ATR(Length = atrPeriod);
def nLoss = atrMultiplier * atr;

rec xATRTrailingStop = if close > xATRTrailingStop[1] and close[1] > xATRTrailingStop[1] then
    Max(xATRTrailingStop[1], close - nLoss)
else if close < xATRTrailingStop[1] and close[1] < xATRTrailingStop[1] then
    Min(xATRTrailingStop[1], close + nLoss)
else if close > xATRTrailingStop[1] then
    close - nLoss
else
    close + nLoss;

def pos = if close[1] < xATRTrailingStop[1] and close > xATRTrailingStop[1] then 1
          else if close[1] > xATRTrailingStop[1] and close < xATRTrailingStop[1] then -1
          else pos[1];

def theLong = pos == 1 and pos[1] != 1;
def theShort = pos == -1 and pos[1] != -1;

plot scanB = theLong within 2 bars ;
#plot scanS = theShort within 2 bars;

this is what I got 15 min scan on the short side just now

I like the sound of this script. Any suggestions on using different lengths for intraday like 10 minutes
