[john3]

Hello,

Would someone please convert this from Ninja to Thinkorswim?

I appreciate it.

I am also interested in this if anyone can convert it.

I don't understand how the hh and ll in the NT script is working. It is also interesting that max and min values are initialized on startup and not updated.

@john3 Try this. I'm not sure how close i was able to get it. Let me know how far it is off. I don't have NinjaTrader to compare.

def l = if useHighLow then low else close;
def minL = Lowest(l, length);

def Retracement = retrace/100;
def BuyPrice = ll + (Retracement * MyRange);
def SellPrice = hh - (Retracement * MyRange);

plot DownArrow = if showArrows and !isTrend && isTrend[1] then yes else no;
DownArrow.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);

# Color Bars

AssignPriceColor(if colorBars and isTrend then Color.GREEN else if colorBars then Color.RED else Color.CURRENT);

# Alerts

Alert(isTrend and !isTrend[1], "Up Trend", Alert.BAR, Sound.Ding);
Alert(!isTrend && isTrend[1], "Down Trend", Alert.BAR, Sound.Ding);

@barbaros Thank you very much, but it doesn't seem to match the Ninja's version. Maybe the issue is that changing the settings in the code doesn't seem to change anything. For example, I've changed "length" and "useHighLow," but it didn't seem to do anything.

@john3 I might have messed something up in the translation. I updated the previous post. May be try that version.
