an arrow after close above the previous high

[appplejack003]

Hi guys,
I'm trying to create an indicator that meets the following criteria but so far it hasn't worked.

Conditions:
1.Current close must be higher than the high of the previous bar.
2.Current close must be higher than the high of any of the last 3 bars.
3.Paint an arrow when these conditions are met.

Nothing happens on my chart and I don't know why.

Here is the code below:


#Declare variables
declare lower;

input numBars = 3;

#Define conditions
def currClose = close;
def prevHigh = high[1];
def pastHigh = highest(high, numBars);

#Paint arrow when conditions are met
plot arrowUp = if currClose > prevHigh and currClose > pastHigh then low - 1 else double.nan;
arrowUp.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
arrowUp.SetDefaultColor(Color.GREEN);
arrowUp.SetLineWeight(2);


Thanks!

Thanks!

zoom way out ( click and drag on price axis) and look for arrows near 0 line.

your plot specified a price level, but you used boolean arrows.
remove 'boolean_' from arrow code line

or
change the plot line formula to be of a true/false value

plot arrowUp = if currClose > prevHigh and currClose > pastHigh then 1 else 0;

Applejack,

I worked on the code with and without the corrections suggested above and couldn't get it to work no matter what I did for a couple of minutes. Then I realized that requiring the currClose to be higher than pastHigh involved requiring the current candle's close to be higher than the current candle's high, which is impossible. In addition, since pastHigh is included in prevHigh those two definitions are redundant.

Another thought is that the original code says "declare lower" and I couldn't make an arrow-based indicator work properly in the indicator box below the chart.

I wrote a script that I think meets your requirements. A picture is shown below.

I wanted to make your 3 previous candles definition an input-adjustable number so that, for example, one could easily change it to require a close to be higher than the highs of the past 5 or 10 bars, etc., instead of 3 bars. I think it will be possible by including "displace" in the code appropriately, but I need to do a little more work on it to be sure it's right and that it excludes the high of the current bar. I'm posting the code below because it certainly seems to work correctly.

# CloseAbove3Highs
# applejack003 question

#Define conditions
def currClose = close;

#Paint arrow when conditions are met
plot arrowUp = currClose > high[1] and currClose > high[2] and currClose > high[3];

arrowUp.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
arrowUp.SetDefaultColor(Color.GREEN);
arrowUp.SetLineWeight(2);

Okay, this is working. I normally associate the displace command with simply shifting moving averages forwards or backwards by some number of bars on a chart, but it is more useful than I realized.

Here is version 2. The current close can be required to be higher than the highs of any number of previous bars that is desired by changing the input length, and the current bar's high will be excluded from the calculation. I changed the number of previous bar highs from 3 to 10 in the chart below and it changed properly to be different from the chart that was posted earlier.

# CloseAbove3Highs_v2
# applejack003 question

input length = 3;
input displace = 1;

def currClose = close;

plot arrowUp = currClose > highest(high[displace], length);

arrowUp.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
arrowUp.SetDefaultColor(Color.GREEN);
arrowUp.SetLineWeight(2);
