Control height of arrow plots and other painting strategies?

[Glefdar]

Hi all,

I would like to change the height of signal arrows that are plotting from a study, because I'm using another study that displays values ("PaintingStrategy.values_above" and "PaintingStrategy.values_below"), and when the arrow signals are generated, the arrows cover up the values that display underneath and over the candles. Is there a way to control this?

Post the code and I will show you. The arrows are put at the high or low by default, but you can do high+1 or high*1.05 or anything.

Thanks for offering! It's the Halftrend indicator from this thread, this is the section of the code with the arrow plot attributes:

def buyTrigger = buy_criteria[-1] ;
plot buyTriggerPlot = if buyTrigger[1] and (lowavg[0]>=lowavg[1]) then plotLow else Double.NaN;
buyTriggerPlot.SetDefaultColor(GlobalColor("VividCyan"));
buyTriggerPlot.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
buyTriggerPlot.SetLineWeight(1);
buyTriggerPlot.HideTitle() ;

def sellTrigger = sell_criteria[-1] ;
plot sellTriggerPlot = if sellTrigger[1] then plotHigh else Double.NaN;
sellTriggerPlot.HideBubble() ;
sellTriggerPlot.HideTitle() ;
sellTriggerPlot.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
sellTriggerPlot.SetLineWeight(5);
sellTriggerPlot.SetDefaultColor(Color.LIGHT_ORANGE) ;

You cannot control boolean arrows for all other signals, add the following code before your plots. Change the "0.3" higher or lower to meet your requirements:

# ########################################################
# charting & formatting
def arrow_plots = high – low;
def plotHigh    = high + arrow_plots * 0.3;
def plotLow     = low  - arrow_plots * 0.3;
# ########################################################

Is there a reason that I can't just change the boolean arrows to non-boolean ones? Maybe I'm missing some basic conceptual point about this because it seems to me like if the "SellTrigger" condition is still controlling whether the arrow will be plotted, it can be plotted correctly regardless of whether it's specified as a boolean arrow or not.

EDIT: Changing BOOLEAN_ARROW_UP to ARROW_UP seems to work fine, at least in this case. Thanks for your help!

Yep, on this code you can just change the boolean arrows to non-boolean. To use MerryDay's way, it would be this:
(Remove old def plotHigh and def plotLow) Let me know if it works.

# ########################################################
# charting & formatting
def arrow_plots = high – low;
def plotHigh    = high + arrow_plots * 0.3;
def plotLow     = low  - arrow_plots * 0.3;
# ########################################################
def buyTrigger = buy_criteria[-1] ;
plot buyTriggerPlot = if buyTrigger[1] and (lowavg[0]>=lowavg[1]) then plotLow else Double.NaN;
buyTriggerPlot.SetDefaultColor(GlobalColor("VividCyan"));
buyTriggerPlot.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
buyTriggerPlot.SetLineWeight(1);
buyTriggerPlot.HideTitle() ;

def sellTrigger = sell_criteria[-1] ;
plot sellTriggerPlot = if sellTrigger[1] then plotHigh else Double.NaN;
sellTriggerPlot.HideBubble() ;
sellTriggerPlot.HideTitle() ;
sellTriggerPlot.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);
sellTriggerPlot.SetLineWeight(5);
sellTriggerPlot.SetDefaultColor(Color.LIGHT_ORANGE) ;

Worked great. Thank you both!
