Sorry I'm new to Thinkscript.

I'm try to plot a arrow on every 4 consecutive down day (close to close), and 5 consecutive up day.

===
Plot Down4Day = close < close[-1] and close[-1] < close[-2]
and close[-2] < close[-3]
and close[-3] < close[-4]
;

Down4Day.SetPaintingStrategy(PaintingStrategy.Boolean_ARROW_UP);

Plot Up5Day = close > close[-1] and close[-1] > close[-2]
and close[-2] > close[-3]
and close[-3] > close[-4]
and close[-4] > close[-5]
;

Up5Day.SetPaintingStrategy(PaintingStrategy.Boolean_ARROW_Down);

====

but after I apply this code to a chart, the arrows are no where near what it should be. Anything would be helpful!!!

Thanks in advance!!!

The period number without the negative looks back:

 

Code

Plot Down4Day = close < close[1] and close[1] < close[2] and close[2] < close[3] and close[3] < close[4]; Down4Day.SetPaintingStrategy(PaintingStrategy.Boolean_ARROW_UP); Down4Day.SetDefaultColor(Color.GREEN); Plot Up5Day = close > close[1] and close[1] > close[2] and close[2] > close[3] and close[3] > close[4] and close[4] > close[5]; Up5Day.SetPaintingStrategy(PaintingStrategy.Boolean_ARROW_Down); Up5Day.SetDefaultColor(Color.Red);

Cool. Thx!

Consecutive equal conditions can be optimized by sum function for example the two following conditions returns equal results::

1. sum(close>close[1],3) == 3

2. close>close[1] and close[1]>close[2] and close[2]>close[3]

Hi,

The "sum" instructions is shorter (in number of characters) but I think that it is slower (in execution time).

It requires three evaluations of the condition whereas the "and" is supposed to return FALSE if the first condition is FALSE, without evaluating the two others.

Yes, Nicolas, it sure is. This is just an example of using boolean return in mathematical operations
I've seen alot of studies with statements like:
def c = if a>b then 1 else 0;
actually there is no need to assign 1 or 0 such way, the optimized equation would be simply
def c = a>b;
