DEMA Crossover with Heikin-Ashi Candle Confirmation for ThinkorSwim

[blackbox]

I ported this over to Easylanguage for Tradestation - I didn't know that TOS didn't have autotrading. Either way... strategy still holds up in Tradestation going forward testing for futures. Equities might be harder since there can be a lot of overnight movement. Weekends are the mostly the only issue with Futures.

Anyway you could share the tradestation code for this strategy? Thank you

Does anyone have access to the tradestation code for this strategy? @DaGekko @blackbox

Please use the DEMA_HA code with caution - the way it is built gives an advantage in the back-test that is very difficult to repeat in live trading. The three lines of code that cause an issue in my view are:

def demaCrossingOverGoingUp = demaSlow < demaFast and demaSlow[-1] > demaFast[-1];

AddOrder(OrderType.SELL_AUTO, sell equals 1, open, 100, Color.RED, Color.RED, "Sell @" + open);
AddOrder(OrderType.BUY_AUTO, buy equals 1, open, 100, Color.GREEN, Color.GREEN, "Buy @" + open);

I tested with 8 tick Range Bars with over 5000 trades and then did an Out of Sample test. With this code I could not repeat the back-test results because many of the entries could not be made as signaled with this code.

Made a few changes in the code.

def demaSlow = DEMA(close, 8);#8
def demaFast = DEMA(close, 21);#21
plot demaFastlt = DEMA(close, 50);#50
demaFastlt.SetLineWeight(2);
plot demaFastvlt = DEMA(close, 200);#200
demaFastvlt.SetLineWeight(4);

def HAclose = ohlc4;
def HAopen = CompoundValue(1,(HAopen[1] + HAclose[1]) / 2,
(open[1] + close[1]) / 2);
def HAhigh = Max(Max(high, HAopen), HAclose);
def HAlow = Min(Min(low, HAopen), HAclose);

def demaCrossingOverGoingDown = demaSlow[1] > demaFast[1] and demaSlow < demaFast;
def demaCrossingOverGoingUp = demaSlow < demaFast and demaSlow[-1] > demaFast[-1];

def HARed = HAOpen > HAclose;
def HAGreen = !HARed;
def HADecidedRed = HARed and HAHigh == HAopen;
def HADecidedGreen = HAGreen and HAlow == HAOpen;

Hi my friend. Please, Where can I find this script to use it in the TOS Scanner tool to search for Stocks that have the indicator (DEMA HA) shown in the study to perform Call operations?
Thanks

 

[harber09]

How do we scan for buy and sell signals on the daily?

 

[BenTen]

@harber09 The script provided in this thread is a backtesting strategy; here is the modified version of it to be used as an indicator. I added the buy and sell arrows to help you scan for signals.

def demaSlow = DEMA(close, 8);
def demaFast = DEMA(close, 21);

def HAclose = ohlc4;
def HAopen = CompoundValue(1,(HAopen[1] + HAclose[1]) / 2,
(open[1] + close[1]) / 2);
def HAhigh = Max(Max(high, HAopen), HAclose);
def HAlow = Min(Min(low, HAopen), HAclose);

def demaCrossingOverGoingDown = demaSlow[1] > demaFast[1] and demaSlow < demaFast;
def demaCrossingOverGoingUp = demaSlow < demaFast and demaSlow[-1] > demaFast[-1];

def HARed = HAOpen > HAclose;
def HAGreen = !HARed;
def HADecidedRed = HARed and HAHigh == HAopen;
def HADecidedGreen = HAGreen and HAlow == HAOpen;

def sell = demaCrossingOverGoingDown and (HADecidedRed or HADecidedRed[1] or HADecidedRed[2]);

def buy = demaCrossingOverGoingUp and (HADecidedGreen or HADecidedGreen[1] or HADecidedGreen[2]);

# Plot Confirmed Signals
plot bullish = buy;
bullish.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
bullish.SetDefaultColor(Color.CYAN);
bullish.SetLineWeight(1);
plot bearish = sell;
bearish.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
bearish.SetDefaultColor(Color.MAGENTA);
bearish.SetLineWeight(1);

 

[Echeveste]

Hello,
How could I apply the code to work in my whatchlist and/or make a sound when a buy or sell happens?
Thank you!

Can I save it as a study and use auto buy condition to execute automatically?
Thanks

 

[BenTen]

@Echeveste ThinkorSwim does not support auto trading at the moment. That script is only for backtesting.

 

[hexis777]

@mcdon030 Please., Could you create a script to scan the variable "DEMA HA" in the TOS Scan tool? Thank You

 

[Moose]

@mcdon030 Did you get this code tested? does it give an actual results after you made the changes? Thank you

 

[blackbox]

Hi! I was just looking for some clarity regarding the DEMA + HA strategy posted here:

The [-1] bars for the going up signal is throwing me off. Does that mean it is looking into the future to create the signal? but the going down seems normal. Would that cause a delay in the signal?

Thank you so much for your time!

 

[csrkk]

@BenTen Sometimes I am not seeing Bullish Signal though the candle looks green and price go up. Is this fully tested? Can you please confirm.

 

[BenTen]

@csrkk Do you have an example? If so, please post a screenshot of it. That way I can investigate.

@hexis777 Use the code from message #45 and scan for the up/down arrows.

hi my friend, thanks for your help., Comparing the strategy script in message #19, the position "DEMA HA" Bubble is different or not displayed using the script in message #45. Could you please create a scan script based on the script from message #19.
Thank you so much

Using script in Message #19 (is very good)

Using script in Message #45

@hexis777 Here is the modified code based on the script from message #19. I added up and down arrows so you can use it with the scanner.

def HAlow = Min(Min(low, HAopen), HAclose);

def demaCrossingOverGoingDown = demaSlow[1] > demaFast[1] and demaSlow < demaFast;
def demaCrossingOverGoingUp = demaSlow < demaFast and demaSlow[-1] > demaFast[-1];

Thanks Ben, it works well

 

[hexis777]

Master @BenTen , Please help us with a script to search and get the result of "DEMA Buy @" green color
Thanks a lot ,)

 

[BenTen]

@hexis777 I assume you are referring to the script I posted in message #54. If so, watch the video from this thread. Scan for bullish signals.

Hi master, the script from message # 54 works fine to only search for arrows pointing up., But what I would like please is to search for the value "DEMA Buy @ ..." which cannot be done with the script from message # 54
Thanks ,)

 

[BenTen]

@hexis777 Where is the DEMA Buy label coming from? Post the script for that.
