ThinkorSwim coding Thinkscript It's one chart, to be in one strategy

Just use the code from the DEMA indicator. Here is what I would do for a very simple crossover entry:

 

Code

inputs: Price(Close), DEMASlowLength(9), DEMAFastLength(12) ; vars: DEMA_Fast(0), DEMA_Slow(0) ; DEMA_Slow = DEMA(Price, DEMASlowLength) ; DEMA_Fast = DEMA(Price, DEMAFastLength) ; if DEMA_Fast crosses over DEMA_Slow and MarketPosition <> 1 then buy this bar at close ; If DEMA_Slow crosses over DEMA_Fast and MarketPosition <> -1 then sellshort this bar at close ;

it's always the case, something very simple and Easy

How would I translate these to EasyLanguage

This is ThinkScript terminology

def price = close;
def length = 6;
def Displace = -1;
#above provided as inputs

#1
def isNaNPrice = IsNaN(price);
def varLength = Sum(!isNaNPrice, DMA_length);
def varSum = Sum(if isNaNPrice then 0 else price, DMA_length);

plot DMA = if IsNaN(price) or varLength == 0 then Double.NaN else varSum / varLength;
DMA.DefineColor("Displaced", CreateColor(0, 30, 30)); #Lt.Gray
DMA.DefineColor("Effective", CreateColor(0, 30, 30));
DMA.AssignValueColor(if isNaNdPrice then DMAH.Color("Effective") else DMA.Color("Displaced"));
DMA.SetStyle(Curve.SHORT_DASH);

#2
plot EMA = ExpAverage(price, EMA_lenght);
EMA.SetDefaultColor( CreateColor(0, 30, 30)); #Lt.Gray
EMA.SetStyle(Curve.SHORT_DASH);

#3
plot Displacer = price[Displace];
Displacer.SetDefaultColor( CreateColor(0, 30, 30)); #Lt.Gray
Displacer.SetStyle(Curve.SHORT_DASH);

I don't think you need to code this. I don't know Thinkscript, but I am guessing what you want is this indicator: Mov Avg DEMA

It looks like it has the displacement you need, too.

I tried DEMA it did not plot the same as Thinkorswim plots with the same numbers I used in TOS
and when I enter a negative number on EasyLaungage it errors

Negative displaces should not be a problem. I use them with the Alligator indicator (and variants). I was able to plot with a negative displace (TS 10):



Here is the DEMA code:

 

Code

inputs: Price( Close ) [ DisplayName = "Price", ToolTip = "Enter an EasyLanguage expression to use in the exponential moving average calculation."], Length( 9 ) [ DisplayName = "Length", ToolTip = "Enter the number of bars used in the calculation of the smoothing factor used in the calculation of the moving average."], Displace( 0 ) [ DisplayName = "Displace", ToolTip = "Displacement. Enter the number of bars by which plots will be displaced. Displacement may be positive (left) or negative (right)."]; variables: AvgDEMA( 0 ); AvgDEMA = DEMA( Price, Length ); if Displace >= 0 or CurrentBar > AbsValue( Displace ) then begin Plot1[Displace]( AvgDEMA, !( "DEMA" ) ); { alert criteria } if AlertEnabled and Displace <= 0 then begin if Price > AvgDEMA and AvgDEMA > AvgDEMA[1] and AvgDEMA[1] <= AvgDEMA[2] then Alert( !( "Indicator turning up" ) ) else if Price < AvgDEMA and AvgDEMA < AvgDEMA[1] and AvgDEMA[1] >= AvgDEMA[2] then Alert( !( "Indicator turning down" ) ); end; end;

I have a dilemma, I have a strategy in TOS I would like to create in EasyLanguage however I not sure how to do it. It has a negative displacement on price. See diagram.

this is how it shows in TOS

This is how it shows in Easylanguage I need both lines back i position
Is there a way to do this, as it is in TOS
Plot Yellow = ( Close[1 ] )
Plot Mag = ( Close[-1] )

I think I got it, have to test a bit

OK I can get it to Plot just as in TOS, however when placed in a strategy it will not detect the cross overs as plotted
