VolatilitySwitch Questions

Hi all,

I’m trying to change the VolatilitySwitch indicator from a lower study to a study in my upper chart/price area, then add a label and a chart bubble when the indicator hits its highest level or 100%. I’ve moved the indicator up to the price area, plotted a “high” so I can use it for the label (the indicator already has a midline which I left in the code), and defined a "highsignal" so I can use it for the chart bubble. The label is working the way I want it to so I don't need any label help. I’m having two issues with the chart bubble: the first issue is that multiple bubbles are appearing at the very top of the screen which I think may be because of the “declare lower” line still in the code. However, when I remove that line, the entire indicator stops appearing in my upper chart altogether so I don’t know what to do but keep that line in the code. The second issue is that I only want one bubble to appear when the indicator first hits 100%; I don’t want the bubble to reprint for every candle as long as the indicator remains at its high. However, when the indicator goes down and then hits 100% again, I want to get a new bubble. (The label stays on during the entire time the indicator is at 100% but I only want one bubble to appear when the indicator first hits 100%.)

I need help getting the bubble to appear above the candle when the indicator first hits 100% instead of appearing at the top of the screen with multiple candles in a row. I’m new to coding and have only gotten to the point where I am by looking through this website and reading up on the thinkorswim Learning Center. Thanks for any help you can provide.

Here's the code with italicized notes showing changes I’ve made to the VolatilitySwitch's original code:


declare lower;

input length = 21;


#code added for aggperiod

def price2 = close(period = aggregationPeriod.TWO_Min);

Assert(length > 0, "'length' must be positive: " + length);


def dailyReturn = (price2 - price2[1]) / ( (price2 + price2[1]) / 2 );

def histVolatility = StDev(dailyReturn, length);


plot VolatilitySwitch = ( fold i = 0 to length with count do count + if histVolatility <= histVolatility then 1 else 0 ) / length;

plot MidLine = 0.5;

plot High = 1.0;#code added


def HighSignal = volatilityswitch >= High;#code added


VolatilitySwitch.DefineColor("Trending", Color.UPTICK);

VolatilitySwitch.DefineColor("Mean-Reverting", Color.DOWNTICK);

VolatilitySwitch.AssignValueColor(if VolatilitySwitch >= High then VolatilitySwitch.Color("Mean-Reverting") else VolatilitySwitch.Color("Trending"));

MidLine.SetDefaultColor(GetColor(7));



#AddLabel and AddChartBubble code added

AddLabel(yes, "2 Min VS", if volatilityswitch >= High then createcolor(249,233,167) else color.BLACK);#label background is black until condition is met

AddChartBubble(Highsignal, high, "2m", createcolor(249,233,167), no);

the fold loop is comparing a variable to itself , histVolatility ,
so it will always be 1
do count + if histVolatility <= histVolatility then 1 else 0
original has an offset,
do count + if histVolatility <= histVolatility then 1 else 0


to find just the first occurance of a series, look at the previous bar for a different value and check the current bar.
def HighSignal = volatilityswitch[1] < High and volatilityswitch >= High;

or use crosses above
def HighSignal = volatilityswitch crosses above High;


you are using variable names already assigned to constants. don't do that
plot High = 1.0;#code added
rename it to high1 or something

----------------------

i started over with the original code

make 2nd agg an input for user to change, not just 2 min
can input a minimum limit for the trigger, default is 100%
show a label when VolatilitySwitch * 100 is >= the minimum limit
show a bubble above the high, when VolatilitySwitch * 100 is >= the minimum limit


Code: 
# VolatilitySwitch_01

# https://usethinkscript.com/threads/volatilityswitch-from-lower-to-upper-study.18058/

def na = double.nan;
def bn = barnumber();

input price = close;
input length = 21;
#Assert(length > 0, "'length' must be positive: " + length);

def chartagg = getaggregationperiod();
def chartmin = chartagg/(1000*60);

input price_agg = aggregationPeriod.TWO_Min;

# if agg time is < chart time, set the agg time to chart time
def price2;
def aggmin;
if price_agg < chartagg then {
  price2 = close(period = chartagg);
  aggmin = chartagg/(1000*60);
} else {
  price2 = close(period = price_agg);
  aggmin = price_agg/(1000*60);
}

input price_data = {chart_time , default secondary_agg};
# choose data source , 2nd agg data or chart data
def pr;
def mins;
switch(price_data) {
case chart_time:
  pr = close;
  mins = chartmin;
case secondary_agg:
  pr = price2;
  mins = aggmin;
}


def dailyReturn = (price2 - price2[1]) / ( (price2 + price2[1]) / 2 );

Thanks @halcyonguy. This is helpful and it's working. I'll get back to you if I have any questions.

Hi all,

Is there a way to count how many MTF indicators are at their high point at one time? I have multiple copies of the VolatilitySwitch indicator set up for different timeframes that I use on the 2-minute chart (the timeframes are 2-, 3-, 4-, 5-, 10-, 15-, 20-, 30-min, and 1-hr). The code for all of them is the same except for the agg period. I would like a chart bubble and alert whenever at least 6 of them are at their high point at the same time. If all of these need to be combined into one indicator before counting is even possible, let me know. I appreciate any help you can provide.

declare lower;

input length = 21;

def price2 = close(period = aggregationPeriod.TWO_Min);

Assert(length > 0, "'length' must be positive: " + length);

def dailyReturn = (price2 - price2[1]) / ( (price2 + price2[1]) / 2 );
def histVolatility = StDev(dailyReturn, length);

plot VolatilitySwitch = ( fold i = 0 to length with count do count + if histVolatility <= histVolatility then 1 else 0 ) / length;
plot MidLine = 0.5;
plot High1 = 1.0;

def HighSignal = volatilityswitch >= High1;

VolatilitySwitch.DefineColor("Trending", Color.UPTICK);
VolatilitySwitch.DefineColor("Mean-Reverting", Color.DOWNTICK);
VolatilitySwitch.AssignValueColor(if VolatilitySwitch >= MidLine then VolatilitySwitch.Color("Mean-Reverting") else VolatilitySwitch.Color("Trending"));
MidLine.SetDefaultColor(GetColor(7));

#AddLabel(yes, "2 Min VS", if volatilityswitch >= High then createcolor(249,233,167) else color.BLACK);

AddChartBubble(Highsignal, high1 + (high1*.02), "2m", createcolor(249,233,167), no);

EDIT - updated to have a label for count of green signals
can set a minimum quatity to trigger. default is 6.


======================
this is a lower study
that calcs VolatilitySwitch for 8 aggregations
it can plot lines or dots
the smallest agg time is at the bottom
the lines are pulses , 0 or 1, for low and high
the dots are green or red, green for a high

Thanks for doing this, Halcyonguy. Is there a way to count the bubbles and get an alert when at least 6 of them are green? It doesn't matter which 6.

Hi all,
RE: Add down arrow to upper chart based on lower study with ability to change arrow's color

I'm trying to add a down arrow above the candles on my chart whenever the same conditions are met as the label at the bottom of the code. I want to be able to change the color of the arrow. I appreciate any help you can provide.
Ruby: 
declare lower;

input length = 21;

def price3 = close(period = aggregationPeriod.THREE_Min);


Assert(length > 0, "'length' must be positive: " + length);

def dailyReturn = (price3 - price3[1]) / ( (price3 + price3[1]) / 2 );
def histVolatility = StDev(dailyReturn, length);

plot VolatilitySwitch = ( fold i = 0 to length with count do count + if histVolatility <= histVolatility then 1 else 0 ) / length;
plot MidLine = 0.5;
plot High1 = 1.0;

def HighSignal = volatilityswitch >= High1;

#VolatilitySwitch.DefineColor("Trending", Color.UPTICK);
#VolatilitySwitch.DefineColor("Mean-Reverting", #Color.DOWNTICK);
#VolatilitySwitch.AssignValueColor(if VolatilitySwitch >= #MidLine then VolatilitySwitch.Color("Mean-Reverting") #else VolatilitySwitch.Color("Trending"));

VolatilitySwitch.DefineColor("On", Color.UPTICK);
VolatilitySwitch.DefineColor("Off", Color.DOWNTICK);
VolatilitySwitch.AssignValueColor(if VolatilitySwitch >= High1 then VolatilitySwitch.Color("On") else VolatilitySwitch.Color("Off"));

AddLabel(yes, "3 Min VS", if volatilityswitch >= High1 then createcolor(249,188,179) else color.BLACK);

the fold loop is comparing a variable to itself , histVolatility ,
so it will always be 1
do count + if histVolatility <= histVolatility then 1 else 0
original has an offset,
do count + if histVolatility <= histVolatility then 1 else 0


to find just the first occurance of a series, look at the previous bar for a different value and check the current bar.
def HighSignal = volatilityswitch[1] < High and volatilityswitch >= High;

or use crosses above
def HighSignal = volatilityswitch crosses above High;


you are using variable names already assigned to constants. don't do that
plot High = 1.0;#code added
rename it to high1 or something

----------------------

i started over with the original code

make 2nd agg an input for user to change, not just 2 min
can input a minimum limit for the trigger, default is 100%
show a label when VolatilitySwitch * 100 is >= the minimum limit
show a bubble above the high, when VolatilitySwitch * 100 is >= the minimum limit


Code: 
# VolatilitySwitch_01

# https://usethinkscript.com/threads/volatilityswitch-from-lower-to-upper-study.18058/

def na = double.nan;
def bn = barnumber();

input price = close;
input length = 21;
#Assert(length > 0, "'length' must be positive: " + length);

def chartagg = getaggregationperiod();
def chartmin = chartagg/(1000*60);

input price_agg = aggregationPeriod.TWO_Min;

# if agg time is < chart time, set the agg time to chart time
def price2;
def aggmin;
if price_agg < chartagg then {
  price2 = close(period = chartagg);
  aggmin = chartagg/(1000*60);
} else {
  price2 = close(period = price_agg);
  aggmin = price_agg/(1000*60);
}

input price_data = {chart_time , default secondary_agg};
# choose data source , 2nd agg data or chart data
def pr;
def mins;
switch(price_data) {
case chart_time:
  pr = close;
  mins = chartmin;
case secondary_agg:
  pr = price2;
  mins = aggmin;
}


def dailyReturn = (price2 - price2[1]) / ( (price2 + price2[1]) / 2 );
def histVolatility = StDev(dailyReturn, length);

def VolatilitySwitch = ( fold i = 0 to length with count do count + if histVolatility[i] <= histVolatility then 1 else 0 ) / length;

def volsw =  VolatilitySwitch * 100;
input min_limit = 100.0;

def firsthi = if bn == 1 then 0
 else if Volsw[1] < min_limit and Volsw >= min_limit then 1
 else 0;


input show_labels = yes;
addlabel(show_labels, "data agg min " + mins, color.light_gray);


AddLabel(
 show_labels and firsthi,
 "VS " + volsw ,
 color.yellow);
# createcolor(249,233,167));


input show_bubble = yes;
addchartbubble(
 show_bubble and firsthi,
 high,
 "vol sw\n" + VolatilitySwitch,
 color.yellow,
 yes);

@halcyonguy, I want to thank you again for helping me with this. It is working really well and I learned some things I didn't know.
