Stoch DMI

[GaMoneyDr]

I am new to ThinkorSwim. I have created a few scans that I really like. I have created a few simple strategies.

I am having difficulty with creating a strategy that has multiple studies, I can't seem to code ThinkScript correctly to accept 2 conditions.

I can create a scan that is pretty complicated and shows me what I want as a "right now" snapshot. But I can't seem to incorporate the same logic into a strategy for a backtest. I have alot to learn, and I will keep reading these forums.

Here is the strategy I have tried to create for the past 3 days.

Thanks for any help, and any advice on putting more than 1 study into a strategy.


1. Full Stochastic: %K is less than 30, and %K crosses above %D
2. DMI: DI+ is above DI-
3. Nice to have Bonus --- ZigZag is sloping upward at the time of the buy point.

GaMoneyDr,

You may have already figured this one out, but if not then this may get you going on the idea.

The script plots an arrow when StochasticFull K is < 30 and K crosses above D while DI+ is above DI-. Signals were extremely rare when the TOS StochasticFull was set at its default 10, 10, 3 values. When I switched it to the more commonly used 14, 3, 3 values some more signals appeared. The StochasticFull and DMI parameters can be changed in the inputs. No ZigZag slope requirement coded yet...

# StochasticAndDMI_Buy
# Question from GaMoneyDr; plots arrow when DI+ > DI- and StochasticFull is oversold and FullK crosses above FullD; Note that then StochasticFull default parameters are 14, 3, 3; these are more common than 10, 10, 3 values found in TOS.

input length = 14;
input averageType = AverageType.WILDERS;

input over_bought = 80;
input over_sold = 30;
input KPeriod = 14;
input DPeriod = 3;
input priceH = high;
input priceL = low;
input priceC = close;
input slowing_period = 3;
input averageType2 = AverageType.SIMPLE;

def hiDiff = high - high[1];
def loDiff = low[1] - low;
def plusDM = if hiDiff > loDiff and hiDiff > 0 then hiDiff else 0;
def minusDM =  if loDiff > hiDiff and loDiff > 0 then loDiff else 0;
def ATR = MovingAverage(averageType, TrueRange(high, close, low), length);
def "DI+" = 100 * MovingAverage(averageType, plusDM, length) / ATR;
def "DI-" = 100 * MovingAverage(averageType, minusDM, length) / ATR;

def lowest_k = Lowest(priceL, KPeriod);
def c1 = priceC - lowest_k;
def c2 = Highest(priceH, KPeriod) - lowest_k;
def FastK = if c2 != 0 then c1 / c2 * 100 else 0;

def FullK = MovingAverage(averageType2, FastK, slowing_period);
def FullD = MovingAverage(averageType2, FullK, DPeriod);

def DMIcond = "DI+" > "DI-";
def StochOversold = FullK < over_sold;
def StochCross = FullK crosses above FullD;

plot BuySignal = DMIcond and StochOversold and StochCross;

BuySignal.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
BuySignal.SetDefaultColor(Color.BLUE);
BuySignal.SetLineWeight(3);

Thank you so much. This is a huge head start on what I was trying to do. Thank you for taking the time to help me. It is greatly appreciated!!
