Best way to identify close above a recent pullback bar

AFL Programming
#1

Hi,

I am trying to identify the bar that closes below recent pull back bar. I can check close below previous bar using Ref() but can't seem to find close if there are more than one pullback bar. I have attached image for describing the scenario

pullback bar

Thanks
Deepak

Take a look at the ValueWhen function.

In my opinion, the key here is how you define “recent pull back bar”? Recent would be something that happened in the last 5 candles, or 50?

You can have a look at the functions HHV and LLV, for when a new maximum or low is hit. Then writing a for loop to see if in a certain number of bars the price pullback below that level.

Hope this helps.

@ak87: no need for a loop in this case. Assuming you have identified the pullback bars, you can use BarsSince() to see how long it’s been since the most recent pullback.

Thanks everyone for your pointers. I was able to plot a close above/below the recent pull back bar with this code

// close above pullback high
isBearBar = C < O;
PBHigh = ValueWhen(isBearBar,H,1);
PBBuy = Cross(C,PBHigh);
PBBuyBarIndex = ValueWhen(PBBuy,BarIndex(),1);
PlotShapes(PBBuy*shapeUpArrow,colorBlue,0,L,-12);

// close below pullback low
isBullBar = C > O;
PBLow = ValueWhen(isBullBar,L,1);
PBShort = Cross(PBLow,C);
PBBuyBarIndex = ValueWhen(PBBuy,BarIndex(),1);
PlotShapes(PBShort*shapeDownArrow,colorRed,0,H,-20);

pullback bar success

Deepak
