Donchian Channel with Fibonacci Zone Indicator for ThinkorSwim


Staff member
Here is the converted version of Fibonacci Zone on TradingView to ThinkorSwim. According to the developer, it was a Donchian Channel but instead of using the median line he added four Fibonacci lines.


How to read the Fibonacci Zone:

  • Blue area is the uptrend zone
  • Grey area is the ranging zone
  • Orange area is the downtrend zone
  • Outside of the mentioned zones is in-betweens

input length = 21;

plot hl = highest(high, length);
plot ll = lowest(low, length);
def range = hl-ll;
plot hf = hl-range*0.236;
plot cfh = hl-range*0.382;
plot cfl = hl-range*0.618;
plot lf = hl-range*0.764;

DefineGlobalColor("Dark_Blue", createColor(0,0,100));
DefineGlobalColor("Dark_Orange", createColor(150,100,0));
DefineGlobalColor("Dark_Gray", Color.Dark_Gray);
AddCloud(hl,hf, GlobalColor("Dark_Blue"), GlobalColor("Dark_Blue"));
AddCloud(ll, lf, GlobalColor("Dark_Orange"), GlobalColor("Dark_Orange"));
