Horizontal line with conditions.

April 8th, 2021, 09:24 AM

Hello,

I'm really new to build a script for thinkorswim.

Recently i've made this script but i'd like to put some condition on it.
1: i want it to show horzontal line only if the gap criteria. ( is above 10% or 30% for example).

def a = Open(period = AggregationPeriod.DAY);
def b = 1.2;
def c = 1.3;
plot push1 = a * b;
plot push2 = a * c;

push1.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
push2.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);

The main idea is to add conditions to the plot lines and return Double.NaN when you don't want lines. Here's an example with your gap requirements.

Hope this helps,
Jay

Code

input minGap = 10;

def a = Open(period = AggregationPeriod.DAY);
def b = 1.2;
def c = 1.3;

def prevClose = close(period = AggregationPeriod.DAY)[1];
def gapPct = Round((a / prevClose - 1) * 100, numberOfDigits = 2);
def day = getDay();
def lastDay = getLastDay();
def isToday = if(day == lastDay, 1, 0);

plot push1 = if isToday and gapPct >= minGap then a * b else Double.NaN;
plot push2 = if isToday and gapPct >= minGap then a * c else Double.NaN;

push1.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
push2.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);

AddLabel(yes, "GapPct: " + gapPct, Color.CYAN);

Thank you!! you also added the label that shows percentage gap in the day!!! that's awesome!

If gaps interest you, try this on a daily chart. It marks every gap greater than a percentage, and determines if it closed the gap or went higher. For this study, I used the previous high to find the gaps rather than previous close. It also aggregates the results of the chart in the label. Not sure if there's any edge here, but may be useful if you are studying gaps.

Code

input gap = 5.0;
input minVolume = 500000;

def todayHigh = high( period = AggregationPeriod.DAY);
def todayLow = low( period = AggregationPeriod.DAY);
def dailyOpen = open(period = AggregationPeriod.DAY);
def todayClose = close(period = AggregationPeriod.DAY);
def prevClose = close(period = AggregationPeriod.DAY)[1];
def newDay = GetYYYYMMDD() != GetYYYYMMDD()[1];

def dailyVol = volume(period = AggregationPeriod.DAY);


#gap calc
def gapPct = Round((dailyOpen - todayHigh[1]) / todayHigh[1] * 100, numberOfDigits = 0);
def minVolReached = dailyVol > minVolume;
def gapCondition = gapPct > gap and newDay and minVolReached;
def gapCount = if gapCondition then 1 + gapCount[1] else gapCount[1];

def totalGapVolume = if gapCondition then totalGapVolume[1] + dailyVol else totalGapVolume[1];

def avgGapVol = Round(totalGapVolume / gapCount, 0);

def closedHigher = if gapCondition and todayClose > dailyOpen then 1 else 0;
def closedGap = if gapCondition and todayLow <= todayHigh[1] then 1 else 0;

def openPeak = todayHigh - dailyOpen;

def closedGapTotal = if closedGap then 1 + closedGapTotal[1] else closedGapTotal[1];
def closedHigherTotal = if closedHigher then 1 + closedHigherTotal[1] else closedHigherTotal[1];

#display
AddLabel(visible = yes, text = 
"Gap Ups > " + gap + 
"%: " + gapCount +
", Closed Gap: " + closedGapTotal +
", Closed Higher: " + closedHigherTotal +
", AvgGapVol: " + avgGapVol
, Color.CYAN);

#produces a date label in MMDDYYYY format
def Year = (Round(GetYYYYMMDD() / 10000, 0));#This produces the year as1,210 
def Month = GetMonth();
def Day = GetDayOfMonth(GetYYYYMMDD());


#mmm, bubbles
AddChartBubble(gapCondition, high, 
"Date: " + Month + "/" + Day + "/" + AsPrice(Year) +
"\nGap: (" + gapPct + "%)" +
"\nVolume: " + dailyVol +
"\nOpen Peak: " + openPeak + 
"\nClose: " + todayClose +
"\nPrevClose: " + prevClose +
"\nOpen: " + dailyOpen +
"\nClosed Higher: " + (if closedHigher then "Yes" else "No") + 
"\nClosed Gap: " + (if closedGap then "Yes" else "No")
, Color.CYAN, yes);

Wow nice seems really a good tool! yeah im really interested in gaps and volume.
