Trying to get script to accurately filter stocks that rise e.g. 2% in volume and price for 3 consecutive weeks

[TOSnewb]

Hi guys, I got a script but it is not exactly working to the tee as I figured there are some tickers that it did not pick up like SBUX where it had 3 rising weeks of both volume and price even though I set the % parameters to 0.5% from initial 2%
My script is as below, can someone enlighten me how could I modify it to pick up tickers accurately?

input price = close;
input length = 3;
input vol = volume;

def twoPercentGainPrice = 100 * (price / price[1] - 1) >= 2.0;
def threeBarsOfGainPrice = twoPercentGainPrice[2] and twoPercentGainPrice[1] and twoPercentGainPrice;

def twoPercentGainVol = 100 * (vol / vol[1] - 1) >= 2.0;
def threeBarsOfGainVol = twoPercentGainVol[2] and twoPercentGainVol[1] and twoPercentGainVol;

plot scan = threeBarsOfGainPrice and threeBarsofGainVol;

Hey @TOSnewb - On which weeks do you think it should have fired but didn't? I looked at your code on SBUX and seems to be working well.

Strange, my scanner is showing TFII, SGRP, NXTFF, FCIC and ZMPLF only, are these showing up for you along with SBUX too?

I am debugging it as an indicator. Can you point to a specific date and ticker when you are getting incorrect results?

Sorry not sure what do you mean, if you meant when did I get incorrect result that'd be everyday and SBUX is the ticker that I found by accident that it should show up in scanner.

Right - so you are looking at an SBUX chart and seeing 3 weeks of increasing volume and increasing price. Can you give me the dates of those 3 weeks?

Ah okay, so it starts from the week of Jul 9, 16 then 23 for SBUX. Scanner is supposed to pick the last 3 weeks' volume and price increment.

OK. Well, you might want to check your formulas for the vol and price % gain, but also you are forgetting that the week of Jul 2 also comes into play. Your formula says 7/23 > 7/16 and 7/16 > 7/9 and 7/9 > 7/2. - Matt.

Hmm okay thanks for your input! Not really fluent at programming and also this script was given by someone as well and thought it worked fine at the start but realised it isn't capturing the entirety and how I'd want it to work.
