# Help With Custom Price & Volume Trending Script

#### cfire23

##### New member
Greetings all,

thank you in advance for any and all assistance with creating a custom ToS script that plots UpArrow below candle where the high is greater than high of previous candle and volume is greater than volume of previous candle/bar. below is the draft script but it doesn't work - please help to get the script to work.

input length = 10;
input paintBars = yes;
input averageType = AverageType.WILDERS;
input price = volume;
input percent = 2;
input Choice = {default greater, less};

def x = 100*(price / price[length]-1);
plot scan;

switch (Choice){
case greater:
scan = x >= percent;
case less:
scan = x <= -percent;
}

DefineGlobalColor("Positive", Color.UPTICK);

plot greenarrow = if high is greater than high from 1 bars ago and Choice is greater than Choice from 1 bars ago then plotLow else Double.NaN;
greenarrow.SetDefaultColor(color.green);
greenarrow.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
greenarrow.SetLineWeight(2);
greenarrow.HideBubble() ;
greenarrow.HideTitle() ;

plot greenarrow = if high is greater than high from 1 bars ago and Choice is greater than Choice from 1 bars ago then plotLow else Double.NaN;
greenarrow.SetDefaultColor(color.green);
greenarrow.SetPaintingStrategy(PaintingStrategy.ARROW_UP);

greenarrow.HideBubble() ;
greenarrow.HideTitle() ;

this is easier if each condition is set to a variable, then the variables used in the plot.

regarding this line,
plot greenarrow = if high is greater than high from 1 bars ago and Choice is greater than Choice from 1 bars ago then plotLow else Double.NaN;

...you can't reference an input variable this way. this is how you check the value of an input variable,
if choice == choice.greater then 1 else 0

...Choice is greater than Choice from 1 bars ago. even if it did work, it makes no sense. choice is a word, not a value. so one word can't be greater than another. did you mean to use x?

...plotlow isn't defined , so there is no value to plot.

maybe this will help
here is an alternative, based on using x instead of choice, and low instead of plot low.
Code:
``````# def h1 = high is greater than high from 1 bars ago
# same thing, coded differently
def h1 = (high > high[1]);

def x1 = (x > x[1]);

plot greenarrow = if ( h1 and x1) then low else Double.NaN;``````

EDIT .
actually almost nothing in your code is related to your rules statement

if this is what you want

plots UpArrow when ,
...high is greater than high of previous candle
and
...volume is greater than volume of previous candle

see how i separated each condition on its own line. it makes it easier to read and code.
then try this

Code:
``````def hup = ( high > high[1] );
def vup = ( volume > volume[1] );

plot z = if (hup and vup) then low else double.nan;
z.SetDefaultColor(color.green);
z.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
z.SetLineWeight(2);
z.HideBubble() ;
#``````

Is there a way to get alerts on current open positions on ThinkorSwim for high of day greater than previous day high or low of day less than previous low of day?

I have created a scan for general tickers, just thinking of adding openP/L script or something to identify my positions price action.

#High of Day greater than Previous Day High
plot hup = ( high("period" = AggregationPeriod.DAY) > high("period" = AggregationPeriod.DAY )from 1 bar ago );

Thank You!

i am not sure about creating a scan. There might be some way to make a study and use getquantity() , to check for existing positions.
Then combine that true/false, with other conditions.
