scanning for price above EMA for certain number of price bars

[vrinx3547]

How can I scan for the price bars closing above a certain EMA for a certain number of price bars in thinkorswim?

EXAMPLE: scanning for price has closed above the 80 ema for 20 price bars.

Thank you.

@vrinx3547 For that you would test for NOT or "!" close crosses below the 80ema within 20 bars...

@vrinx3547 For that you would test for NOT or "!" close crosses below the 80ema within 20 bars...

This will also find symbols that have been below the ema longer than 20 bars. You need to also check that the current close is above the EMA.

i didn't try this in a scan, but i think it will work. it works on a column and on a chart.

possible scan code , (not tested)

input avg1_len = 80;
input avg1_type =  AverageType.EXPONENTIAL;
def ma1 = MovingAverage(avg1_type, close, avg1_len);
input barsback = 20;
plot abovexbars = ( Sum( (close > ma1), barsback ) == barsback );

a column study , that shows for how many bars, close has been above ema for x bars.

def xbarscnt = if bn == 1 then 0 else if !abovexbars then 0 else if (abovexbars and !abovexbars[1] ) then 1 else if abovexbars then xbarscnt[1] + 1 else xbarscnt[1];

plot z = xbarscnt;
z.setdefaultcolor(color.dark_gray);

assignbackgroundcolor( if abovexbars then color.yellow else color.current);

a chart version for testing. draws a count of bar numbers when close is > ema. after x bars of being above, it draws yellow down arrows.

Thank you for this code. Very much appreciated.

Hey, sorry to ask this of you, but I've changed the script slightly to count the number above a 10EMA close, but now I'm having trouble reversing it to count the number of closes beneath the 10EMA for going short, but it keeps equaling 0 or if edited it equals an outrageously high number.

def bn = barnumber();
input barsback = 3;
def abovexbars = (sum (close < movavgexponential(close,10), barsback ) == barsback );

def xbarscnt = if bn == 1 then 0 else if !abovexbars then 0 else if (abovexbars and !abovexbars[1] ) then 1 else if abovexbars then xbarscnt[1] + 1 else xbarscnt[1];

plot z = xbarscnt;
z.setdefaultcolor(color.white);

#assignbackgroundcolor( if abovexbars then color.red else color.current);

Can someone please help out to come up with an script to add the numbers from different time frames when the scanner

# priceaboveEMA_xbars_01 - upper
def bn = barnumber();
input avg1_len = 80;
input avg1_type = AverageType.EXPONENTIAL;
def ma1 = MovingAverage(avg1_type, close, avg1_len);

def abovexbars = ( Sum( (close > ma1), barsback ) == barsback );

def xbarscnt = if bn == 1 then 0 else if !abovexbars then 0 else if (abovexbars and !abovexbars[1] ) then 1 else if abovexbars then xbarscnt[1] + 1 else xbarscnt[1];

plot z = xbarscnt;
z.setdefaultcolor(color.black);

assignbackgroundcolor( if abovexbars then color.green else color.current);

If your question is, can you scan for multiple-timeframes all in one script, the answer is no.
The scan hacker requires you to choose one timeframe to filter your conditions on.
There is no workarounds.
