im back again 🙂  …lol… any way you can help me out with another simple problem with this thinkskript study. what i am trying to achieve is the following as study like this:

Current Bar/TICK  <VOLUME/PRICE>  is   <GREATER/LESS>  <NUMERICAL INPUT>

so it would pretty much be like…current tick for volume is greater than 1K, but i wanna be able to type/choose the <INPUTS> via the thinkorswim GUI

the fartherst i could get is the code below, but i obviously did something wrong because it wont accept the code

 

<pre>

#Wizard text: Current bar’s
#Wizard input: price
#Wizard input: choice
#Wizard text: at least
#Wizard input: length
#Wizard text: periods

input price = volume;
input choice = {default greater, less};
input length = 1000;

plot scan;

switch (Choice){
case “greater”:
scan = sum(price > price[1], length) == length;
case “less”:
scan = sum(price < price[1], length) == length;

</pre>

I’m just shutting down for the day but wanted to make sure I understood the request. I’ll respond late tonight or sometime tomorrow. ”Current tick for volume” is confusing me. Here is your specification:

Current Bar/TICK (VOLUME/PRICE) is (GREATER/LESS) (NUMERICAL INPUT)

I get the Volume/Price: ( select either volume or price)
I get the Greater/Less: (select either greater or less)
I don’t get Current Bar/Tick. Is this supposed to be a choice? Select either Bar or Tick? In this context, what is Tick?

The part I understand is you want to scan for current Bar’s (volume or price) is (greater than or less than) the input value. I need you to clarify what you mean by Tick.

ok, in the picture attached there is a default study for volume tick count percentage, but i dont want percentage, i want it for a for the actual volume.

in charting stock, normally there are a certain amount of “ticks” in every bar, its the smallest amount to analyze, i can settle for bar instead of ticks if you dont know how to define ticks in thinkscript because i couldnt find reference either and i know TOS get their ticks in blocks anyways, vs actual ticks. so end of day even tho i would prefer tick i can settle for bar.

so to reword it…

the volume of the current bar is <greater/less> than <numberical number>

example: the volume of the current bar is greater than 10K

Ah ok. Thanks for providing that screenshot and additional details. I found documentation on that here:  http://toslc.thinkorswim.com/center/reference/thinkScript/Functions/Fundamentals/tick-count.html

It just a price type. (Open, High, Low, Close, Volume and Tick_Count) sort of thing. Notice that Tick_Count is only valid for intraday time frames.

This code should do the trick. Unfortunately there is no way I have found to convert the inputs of a custom scan filter into clickable inputs the way the built in studies work. So in order to change one of the inputs you have to do so directly within the script itself.

For example for the priceType input. You would change that from “volume” to “tick_count” by moving the word default to in front of the “tick_count” option. Likewise for the comparison input.

input priceType = {default "volume", "tick_count"};
input comparison = {default "greater than", "less than"};
input threshold = 1000;
def tradeData = if priceType == priceType."volume" then volume else tick_count;
def signal = if comparison == comparison."greater than" then tradeData > threshold else tradeData < threshold;
plot scan = signal;

lol, almost a year later, this is what i meant to achieve….
the current bar’s volume is at-least (equal or greater than) 30% of the volume bar of the opening bar. (1st bar of the day) (excluding extended hours)

In response to further details provided by Dave on March 14, 2018:

def firstBar = GetDay() <> GetDay()[1] ;
rec firstBarVolume = if firstBar then volume else firstBarVolume[1];
plot scan = !firstBar and volume >= firstBarVolume * 0.3;

Should work. Although I haven’t tested it.

long story short…im just a real tard, but thanks it did work, only problem was i explained it wrong and completely messed up from being in a rush and overwhelmed with this think-script language…. i meant to say:

the current bar’s volume is at-least (equal or greater than) 30% of the of the PRIOR DAYS CLOSING volume bar. (last volume bar of the prior day) (excluding extended hours) by the way thanks for your time and i really appreciate it, i will send you a donation for your time and helpfulness once i have a few extra bucks, might be a few days but less than a month.

Just shift the volume variable one bar to the left:

rec firstBarVolume = if firstBar then volume[1] else firstBarVolume[1];

See that? We use volume[1] in place of volume. This will check for first bar of the day and grab the volume of the previous bar. Which is the last bar of the previous day.
