Scan for stocks above or below simple moving average

February 16th, 2020, 08:59 AM

Hi

Am new here.

Was told TOS script is very powerful and hope to build a script to scan for stocks that is above or below 20 day simple moving. For bullish scan, the previous day close has to be below the 20 day simple moving average. Vice versa for a bearing scan. Attached is a picture for better understanding.

Can somebody teach me how to build? If such script is too difficult, am willing to pay a small fee for your time.

Thanks in advance.

Thinkscript is actually very easy to learn compared to some languages.

NOTE: The code here is Bullish = close > SMA. If you want to change that, simply reverse the > sign

You can use the built-in MovingAverage_Scan that would allow you to use the interface to customize what % you want to be above the SMA.

Here is the code to create a custom scan:

Code

plot signal = if close > SimpleMovingAvg(length=20) then 1 else 0;

You can also create a custom watchlist indicator. In the code below, red means below the 20SMA and green means above the 20SMA

Code

plot signal = if close > SimpleMovingAvg(length=20) then 1 else 0;

signal.AssignValueColor(if signal == 1 then Color.Green else Color.Red);
AssignBackgroundCOlor(if signal == 1 then Color.Green else Color.Red);

Hi trepidation

What i want is that the body of the price (open and close) is within the moving average.

How to define it?

Thanks in advance

Hi, here's your full suite for the indicator.

Scans
Bullish Scan:

Code

input ma_length = 20;
def sma = SimpleMovingAvg(length=ma_length);

plot signal = close > sma && open < sma;

Bearish Scan:

Code

input ma_length = 20;
def sma = SimpleMovingAvg(length=ma_length);

plot signal = open > sma && close < sma;

Watchlist Indicator

Code

input ma_length = 20;
def sma = SimpleMovingAvg(length=ma_length);
def bearish = open > sma && close < sma;
def bullish = close > sma && open < sma;

plot signal = if bullish then 1 else if bearish then 0 else -1;

signal.AssignValueColor(if signal == 1 then Color.Green else if signal == 0 then Color.Red else Color.Black);
AssignBackgroundCOlor(if signal == 1 then Color.Green else if signal == 0 then Color.Red else Color.Black);

SMA + Chart arrows

Code

input maLength = 20;
def sma = SimpleMovingAvg(length=maLength);
def bearish = open > sma && close < sma;
def bullish = close > sma && open < sma;


plot ma = sma;
plot bullSignal = if bullish then low - (0.5 + tickSize())else DOuble.NaN;
plot bearSignal = if bearish then high + (0.5 + tickSize()) else Double.NaN;

bullSignal.SetDefaultColor(Color.UPTICK);
bullSignal.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
bearSignal.SetDefaultColor(Color.DOWNTICK);
bearSignal.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);

Hi trepidation

Thanks for your time and help but I can't achieve what you have shown.

Using your Watchlist Indicator:

input ma_length = 20;
def sma = SimpleMovingAvg(length=ma_length);
def bearish = open > sma && close < sma;
def bullish = close > sma && open < sma;

plot signal = if bullish then 1 else if bearish then 0 else -1;

signal.AssignValueColor(if signal == 1 then Color.Green else if signal == 0 then Color.Red else Color.Black);
AssignBackgroundCOlor(if signal == 1 then Color.Green else if signal == 0 then Color.Red else Color.Black);

Below is my scan result:

OMF is not touching the SMA 20:

XPO also not touching the sma 20:

Its a bullish scan, GFF is below sma 20:

Finally when i use the last code you share, i can't save the script.

Did i do anything wrong? Really appreciate your time and help.

Are you using the right script in the right location? The watchlist and scan only allow for one plot. It looks like you used the watchlist scanner for the scan, the chart study for the watchlist, and didn't use the scan code. The way I set up scan is you can only search for ONLY bearish or ONLY bullish trades.

Here are examples of of each code in action:

BULLISH

Did you figure it out?

Hi trepidation

Sad to say, still not 100% to what you have shown. If i use the 1st code:

input ma_length = 20;
def sma = SimpleMovingAvg(length=ma_length);

plot signal = open > sma && close < sma;

The price bar will be above the SMA.

However if i use the last code:

input maLength = 20;
def sma = SimpleMovingAvg(length=maLength);
def bearish = open > sma && close < sma;
def bullish = close > sma && open < sma;

plot ma = sma;
plot bullSignal = if bullish then low - (0.5 + tickSize())else DOuble.NaN;
plot bearSignal = if bearish then high + (0.5 + tickSize()) else Double.NaN;

bullSignal.SetDefaultColor(Color.UPTICK);
bullSignal.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
bearSignal.SetDefaultColor(Color.DOWNTICK);
bearSignal.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);

I can't save the code. It showed "Exactly one plot expected" at the bottom of page. Why is this?

Thanks again.

I realize I was too ambitious and tried to cover too much ground. Here is your code for bullish scans.

Code

input ma_length = 20;
def sma = SimpleMovingAvg(length=ma_length);

plot signal = close > sma && open < sma;

Hi trepidation

Hope you are well and making tons of money.

The stock market crashed shortly after and didnt have much opportunity to test further the script.

Can you add another condition for me? I want the scan to show stocks that is making a new high as compared to the last price bar. That is to say, i want stocks that are above their 20 sma and when scan today, current price bar has made a higher high as compared to previous day.

Thanks in advance.
