Your code wasn’t good. In your case, you only want to test if the current high is superior to the upper band or if the current low is inferior of the lower bollinger band.
Please find below the modified code that will give you the desired results:
1234567bbup = Average[20](close)+3*std[20]bbdown = Average[20](close)-3*std[20]c1 = high > bbupc2 = low < bbdownSCREENER[c1 OR c2] ((close/DClose(1)-1)*100 AS "%Chg yest.")1 user thanked author for this post.
Here is the small dashboard to show current Close distances from upper and lower Bollinger bands. To have it fixed on chart, it’s a better option to display it on a separate window like I did in my attached example.
This is the dashboard code:
1234567891011defparam drawonlastbaronly=truebbup = Average[20](close)+3*std[20]bbdown = Average[20](close)-3*std[20]updist = (bbup-close)/pipsizedndist = (close-bbdown)/pipsizedrawtext("Distance from BB Top: #updist#pips",barindex,0.5,Dialog,Standard,16) coloured(0,128,255)drawtext("Distance from BB Bottom: #dndist#pips",barindex,0,Dialog,Standard,16) coloured(0,128,255)RETURN1 user thanked author for this post.
Rounding digits is not possible, the only way to do is to modify lines 5 and 6 with this code instead: (it will round the displayed pips text to the next round number).
12updist = round((bbup-close)/pipsize)dndist = round((close-bbdown)/pipsize)1 user thanked author for this post.
How about this for just 2 digits after decimal point… should work (replace all the 100’s with 10 for just 1 digit, or with 1000 for 3 digits, etc…)
