Holy Grail ADX Trading Setup for ThinkorSwim

[endicotto]

Spoiler: It's not the "holy grail". In trading, there is no such thing. This strategy was written by Linda Bradford Raschke and Larry Connors. We kept the name because it sounds cool.

Bullish Direction

• 14-period ADX is above 30 and rising
• Retracement down to 20-period SMA
• Your entry would be at the high of the bar that touches 20-period simple moving average

Bearish Direction

• 14-period ADX is above 30 and rising
• Retracement up to 20-period SMA
• Your short entry would be at the low of the bar that touches 20-period simple moving average

# Start SMA
input price = close;
input length = 20;
input displace = 0;

def SMA = Average(price[-displace], length);
def SMAbull = price > SMA;
def SMAbear = price < SMA;

# Start ADX
input ADXlength = 14;
input ADXaverageType = AverageType.WILDERS;
def ADX = DMI(ADXlength, ADXaverageType).ADX;

def ADXpower = ADX > 30;

def bullish = SMAbull and ADXpower;
def bearish = SMAbear and ADXpower;

AssignPriceColor(if bullish then Color.GREEN else if bearish then Color.RED else Color.WHITE);

I learned about this strategy from here, you should read up on it before using the indicator.

Two things are wrong with that code. Well they are wrong at the source. According to Raschke she uses EMA not SMA. In addition ADX not only has to be above 30 but rising also. Just thought I’d clarify.
