stocks that have gone up x of the last y days

TOS code to find stocks that have gone up x of the last y days (e.g stocks that have gone up 3 of the last 5 days)

Hi, I believe I have seen this code before but cannot find it again.

I would like to have a scan script that would find stocks that were up, say 3 of the last 5 days, and are up 20% during that period.

Can anyone help me with that code?

Thanks in advance.

I believe TOS already has some sort of pre-made scanners for this.

Maybe you can sort by gap-up stocks on the Daily chart?

Thanks BenTen. So you can't think of any script that will allow you to search in the last X periods for symbols that are up Y times (where X would be 5 and Y would be 3 in the example I gave)?

I'm pretty sure I saw some code like that. If I find it, I will post it here.

Adjust as necessary. I've set it to look at Previous Close vs This Close to determine whether it went up. You might prefer Open vs Close. As you see fit.

def lookback = 5;
def up_days = 3;
def is_up = if close > close[1] then 1 else 0;
plot eureka = if sum(is_up, lookback) == up_days then 1 else double.nan;

Note that this finds symbols which are up EXACTLY 3 of the last 5 days. You can replace == with >= if you want 3, 4, or 5 of the last 5 days. All we're really doing is creating an array with 1s and 0s for each period (Day?): a 1 if the day is up and a 0 if the day is not up. Then we sum the array over the last n days (lookback) and decide if it is equal to the number of up days you're looking for.

hope that helps.

Thanks Mashume!

Question: if today's close is below yesterday's, but the previous 4 days were up, will the symbol be plotted, or does today's close need to be up?

Wondering if I would I need to change the is_up variable assignment as follows which would check that at least 1 of the last 3 days were up (which is a requirement for 3 of the last 5 days to be up):

def is_up = if close > close[1] or close[1] > close[2] or close[2] > close[3] then 1 else 0;

Also, is there a difference in output between these statements?

plot eureka = if sum(is_up, lookback) == up_days then 1 else double. Nan;
plot eureka = if sum(is_up, lookback) == up_days then 1 else 0;
