Hi all,
I am new here, I have a code that I wrote in pine editor (trandingview) for a part of my trailing stop algo. I used build in fuction (nz) but I dont know how to use it here so Is there anyone can help me to convert this portion of code to C# ?
AF2 = input(defval=1,title="Percent",minval=0.1)/100
SL2 = Trail1*AF2 // Stop Loss
Trail2 = 0.0
Trail2 := iff(Trail1>nz(Trail2[1],0) and Trail1[1]>nz(Trail2[1],0),max(nz(Trail2[1],0),Trail1-SL2),iff(Trail1<nz(Trail2[1],0) and Trail1[1]<nz(Trail2[1],0),min(nz(Trail2[1],0),Trail1+SL2),iff(Trail1>nz(Trail2[1],0),Trail1-SL2,Trail1+SL2)))

Hi Yusuf,
In this situation, the nz function returns 0 if the previous `Trail2` value is na. We can translate this to C# by first creating a RollingWindow for `Trail1` and `Trail2`.
public RollingWindow<float> Trail1 = new RollingWindow<float>(2); public RollingWindow<float> Trail2 = new RollingWindow<float>(2);We ensure these RollingWindows never return na when trying to access their last elements by adding a 0 to each one at the beginning of the program.
Trail1.Add(0); Trail2.Add(0);Then we can replace the nested if statement that determines the newest Trail2 value with
Trail1.Add(random.Next(0, 1000)); if (Trail1[0] > Trail2[0] && Trail1[1] > Trail2[0]) Trail2.Add(Math.Max(Trail2[0], Trail1[0] - SL2)); else if (Trail1[0] < Trail2[0] && Trail1[1] < Trail2[0]) Trail2.Add(Math.Min(Trail2[0], Trail1[0] - SL2)); else if (Trail1[0] > Trail2[0]) Trail2.Add(Trail1[0] - SL2); else Trail2.Add(Trail1[0] + SL2);See the attached backtest for the full code files. I also recommend reviewing our documentation and completing some bootcamp lessons to learn our API.
Best,
