Show study only on current bar

[AlphaTrader]

HI everybody,

I have a custom study, let's say it's something like:

plot TP;
TP.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
TP.setdefaultColor(color.green);

plot SL;
SL.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
SL.setdefaultColor(color.red);


TP = close + (ATR(21) * 2);
SL = close - ((ATR(21) * 2)/2);

How can I only show the study for the last bar.

With the code above I'm getting this:

But what I want to get this (look at the last bar):

I appreciate your help here.

How can I only show the study for the last bar.

TP = if isNaN(open[-1]) then close + (ATR(21) * 2) else Double.NaN;
SL = if isNaN(open[-1]) then close - ((ATR(21) * 2)/2) else Double.NaN;

TP = if isNaN(open[-1]) then close + (ATR(21) * 2) else Double.NaN;
SL = if isNaN(open[-1]) then close - ((ATR(21) * 2)/2) else Double.NaN;

Works perfect. Thank you!!
