Super Trend indicator

[av.ragavan]

Hi,
I am using SuperTrend indicator mentioned in the below link:
http://www.amibroker.com/members/library/formula.php?id=1505

I would like to sell when the buyprice is less than Close price of 10th bar from Buy. For previous bars, we use Ref(Close,-1) and I am not sure how to code for this case. Could you please guide me or share any link which is similar to it?

Regards,

Maybe using BarsSince ?

You would have to build some code around that, but it would be where I would be looking first....

I would like to sell when the buyprice is less than Close price of 10th bar from Buy.

Your requirement is Nbar Stop.
So for stops either use ApplyStop function or Looping.

As for looping see here

Backtesting, Exit method

Why are you asking whether it is possible? Everything is possible. Below is sample code for snake oil service sellers. SetPositionSize( 100, spsShares ); Buy = Sell = 0; Short = Cover = 0; // buy signal BuySignal = Cross( C, MA( C, 20 ) ); buyentryprice = buyentrybar = 0; for( i = 0; i < BarCount; i++ ) { if( BuySignal[i] && buyentryprice == 0 ) { Buy[ i ] = 1; buyentryprice = BuyPrice[ i ]; buyentrybar = i; } // exit if close is higher than buyprice or if bar is 5th one aft…

If I understand your sentence correctly you would have to modify SellSignal line to

SellSignal = Close[ i ] > buyentryprice AND i == buyentrybar + 10;

Replacing or operator ( || , OR ) by AND operator.
This would check for sell if close is greater than buyprice 10 bars after Buy entry.
So only at that point.

If you want to check >= nbar (instead of ==) then:

SellSignal = Close[ i ] > buyentryprice AND i >= buyentrybar + 10;

I have coded as below for below conditions:
Buy when Close crosses above Supertrend and TSI > 1.85.
Sell when Supertrend crosses above Close or Buyprice crosses above Close price of 10th bar.

//SuperTrend code is copied from Library link: //http://www.amibroker.com/members/library/formula.php?id=1505

//TSI
Ratio = abs(close - Ref(Close, -10)) / ATR(10);
TSI = MA(MA(Ratio,10),100);
Plot(TSI, "TSI", colorRed, styleLine);

//Barsince
B10 = BarsSince(Cross( Close, superTrend ) AND Ref(TSI > 1.85,-1));
B10P = ValueWhen(B10 = 9,C,-9);

//Logical Buy/Sell Rules
Buy = Cross( Close, superTrend ) AND Ref(TSI > 1.85,-1); 
Sell = Cross( superTrend, Close ) OR Cross(BuyPrice,B10P); 

Please correct me if anything wrong in the coding.

Please correct me if anything wrong in the coding.

As mentioned either use ApplyStop or looping code.

SellSignal = Close[ i ] > buyentryprice AND i == buyentrybar + 10;

Replacing or operator ( || , OR ) by AND operator.
This would check for sell if close is greater than buyprice 10 bars after Buy entry.
So only at that point.

If you want to check >= nbar (instead of ==) then:

SellSignal = Close[ i ] > buyentryprice AND i >= buyentrybar + 10;

So instead of upper looping code you may use ApplyStop ValidFrom/To arguments of some profit stop.

In ApplyStop you may use profittarget type and with smallest profit amount (e.g. TickSize) since you just want Close to be greater than Buyprice. And since you want to apply stop only after nbars you can use ValidFrom ValidTo arguments of ApplyStop.

So either profit being valid at nbar after entry (see Close[ i ] > buyentryprice AND i == buyentrybar + nbar). So ValidFrom and ValidTo have to have equal value (last two arguments of below ApplyStop line):

nbar = 9;
amount = 0.01;//Ticksize
exitatstop = 0;
ApplyStop(stopTypeProfit, stopModePoint, amount, exitatstop, False, 0, nbar, nbar);

Note: this may occur very seldom if not at all. So it may be that you get no exit signal or very few only.

---

Or use profit being valid >= nbar (so only ValidFrom being modified):

nbar = 9;
amount = 0.01;//Ticksize
exitatstop = 0;
ApplyStop(stopTypeProfit, stopModePoint, amount, exitatstop, False, 0, nbar);

More detailed code example:

// Your other (Supertrend, TSI) code ABOVE of it

SetOption("ActivateStopsImmediately", False);
SetTradeDelays(0,0,0,0);

BuyPrice = SellPrice = Close;

//Barsince
//Logical Buy/Sell Rules
Buy = Cross( Close, superTrend ) AND Ref(TSI > 1.85,-1); 
Sell = Cross( superTrend, Close ); 

nbar = 9;
amount = 0.01;//Ticksize
exitatstop = 0;
ApplyStop(stopTypeProfit, stopModePoint, amount, exitatstop, False, 0, nbar);

eq = Equity(1,0);

// Plot Buy/Sell Signal Arrows
SellShape = Sell > 0;
PlotShapes(Buy*shapeSquare,colorGreen, 0, L, Offset=-40);
PlotShapes(Buy*shapeSquare,colorLime, 0,L, Offset=-50);
PlotShapes(Buy*shapeUpArrow,colorWhite, 0,L, Offset=-45);
PlotShapes(SellShape*shapeSquare,colorRed, 0, H, Offset=40);
PlotShapes(SellShape*shapeSquare,colorOrange, 0,H, Offset=50);
PlotShapes(SellShape*shapeDownArrow,colorWhite, 0,H, Offset=-45);

@av.ragavan

It seems there is a misunderstanding, my conditions are as below:

Buy when Close crosses above Supertrend and TSI > 1.85.

Sell when Supertrend crosses above Close or Buyprice crosses above Close price of 10th bar.

Buyprice crosses above Close price of 10th bar:

With this condition, I am checking whether the Buyprice is higher than Close of 10th bar. If so, I would like to sell. Idea is not to book profit but to sell when there is no upward price movement from buy after 10bars.

Anyways, thanks for your code, I will explore further.

No, there isn't. You simply changed requirement.
Your first post mentioned:

@av.ragavan

I would like to sell when the buyprice is less than Close price of 10th bar from Buy.

Only later you mentioned "above":

@av.ragavan

Buyprice crosses above Close price of 10th bar.

So then simply use stopTypeLoss instead of stopTypeProfit.

And if using loop then use .... Close[ i ] < buyentryprice .... instead.

Rest of my previous post remains the same.

[av.ragavan]

Please find the code below and let me know whether my understanding is correct.

// Code as below for: When buyprice is greater than close price of 10th bar, book profit.
nbar = 9;
amount = 0.01;//Ticksize
exitatstop = 0;
ApplyStop(stopTypeProfit, stopModePoint, amount, exitatstop, False, 0, nbar);

//Code as below for: When buyprice is lesser than close price of 10th bar, book Loss.
nbar = 9;
amount = 0.01;//Ticksize
exitatstop = 0;
ApplyStop(stopTypeLoss, stopModePoint, amount, exitatstop, False, 0, nbar);
