# Position Risk / Size Calculator w/ Plotted Targets

#### bottomphishing

Having trouble getting the target lines to plot correctly. The problem is they are plotting current trade averages and prior averages for trades I haven't been in in quiet some time. I also added a predetermined stop loss for trades I have not entered yet in order to see my risk real time at the current price. This plots under all candles displayed on the chart. Idk why. Lastly I'm having trouble extending these target plots right. Any help will be greatly appreciated.

Below is the code::

Tried a few things:
To only plot under current candle and not all candles (didnt work):
plot s1 = if (currentPrice - (currentPrice * RiskPercent)) then (currentPrice - (currentPrice * RiskPercent)) else Double.NaN;
s1.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
s1.SetDefaultColor(Color.PINK);

To only plot current trade and not all prior trades since account inception (didnt work)
plot t1 = if TargetPrice then TargetPrice and Extend_to_Right else Double.NAN;
t1.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
t1.SetDefaultColor(Color.GREEN);

Extend_to_right not working either.

I am very new to this my code it prob really sloppy but Im just searching around and trying to piece together something that works our of trial and error.

Hello, just wondering if you ever were able to work out the issues you were having with this study?

This is a older thread, but the first time I'm seeing it. So just incase, here are the fixes requested.
I did have to alter the target levels to get them to fit my chart.

New here. Is there a way to isolate a given value of a bar, specifically the ATR of the bar previous to the bar on which a trade was executed? I'm trying to make an indicator that plots once a position is open but uses factors of the bar previous to the opening bar's ATR to plot Stops and Exits.

I hope this is reasonable place to post this.
