The term Boolean means a result that can only have one of two possible values: true or false.
In ThinkOrSwim, boolean arrows are used on the upper chart.
https://tlc.thinkorswim.com/center/...ingStrategy/PaintingStrategy-BOOLEAN-ARROW-UP
https://tlc.thinkorswim.com/center/...gStrategy/PaintingStrategy-BOOLEAN-ARROW-DOWN
The above script plots an arrow on the first occurrence of a condition being true or not true
plots an up arrow where
close is not > open on the previous bar[1] and close is > open on the current bar.
plots a down arrow where
close > open on the previous bar[1] and close is not > open on the current bar.
Simply change the def condition to equal whatever condition you want to plot the arrow on; to make this snippet work on all your scripts.

plots an up arrow on the low of the candle
https://tlc.thinkorswim.com/center/...ingStrategy/PaintingStrategy-BOOLEAN-ARROW-UP
plots a down arrow on the high of the candle
https://tlc.thinkorswim.com/center/...gStrategy/PaintingStrategy-BOOLEAN-ARROW-DOWN
Usage
Code:
def condition = close > open ;
plot example1 = !condition[1] and condition ;
example1.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
plot example2 = condition[1] and !condition ;
example2.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);plots an up arrow where
close is not > open on the previous bar[1] and close is > open on the current bar.
plots a down arrow where
close > open on the previous bar[1] and close is not > open on the current bar.
Helpful Hint:
if you find yourself adding arrows to your scripts on a regular basis, keep a copy of this script in your study tab:
Code:
#Add Arrows to Any Script
def UPcondition = close ;
def DNcondition = close ;
plot upArrow = !UPcondition[1] and UPcondition;
upArrow.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
upArrow.SetDefaultColor(color.cyan) ;
upArrow.SetLineWeight(1);
plot dnArrow = !DNcondition[1] and DNcondition;
dnArrow.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
dnArrow.SetDefaultColor(color.magenta) ;
dnArrow.SetLineWeight(1);Other Examples
thinkScript can also plot wedges or dots (points) in place of arrows
