Weekly Relative Strength vs SPX

I am trying to create a weekly Relative_Strength indicator that compares a security to the SPX (or other)

I can not seem to get the SPX data using Aggregation Period = weekly.

Here is what I use for the Daily RS_SPX
-------------------------------


input price = FundamentalType.CLOSE;
input RelativeToSecurity = "SPX";
input Lookback = 50;
input smoothingPeriod1 = 8;
input smoothingPeriod2 = 21;

def price1 = Fundamental(price);
def price2 = Fundamental(price, RelativeToSecurity);


def UnderlyingStrength = (price1 - price1[Lookback]) / price1[Lookback];
def BaseStrength = (price2 - price2[Lookback]) / price2[Lookback];

plot RSI = Round((1 + UnderlyingStrength) / (1 + BaseStrength), 3);


-----------------------------

I then look at 2 moving averages to see crosses - defing longer term performance.

I know that I could simply use periods that are 5* the daily period, but that does not provide correct results.

Can anyone help ??

It seems that sometimes I just need to ask the question to get motivated.....

I had tried to do this for a while, but just stumbled upon something. This works:

input price = FundamentalType.CLOSE;
input RelativeToSecurity = "SPX";
input Lookback = 50;


def price1 = CLOSE(period = AggregationPeriod.WEEK);
def price2 = Fundamental(price, RelativeToSecurity, AggregationPeriod.WEEK);


def UnderlyingStrength = (price1 - price1[Lookback]) / price1[Lookback];
def BaseStrength = (price2 - price2[Lookback]) / price2[Lookback];

plot RSI = Round((1 + UnderlyingStrength) / (1 + BaseStrength), 3);

-------------

not using fundamental type for price1 was the key.

Hi, how do i apply these code? do you mind posting a screenshot how the indicator looks like on the chart or scan. Thank you

Hey man, check out the RSMK indicator on TOS. It f*ckin rules, was just added, and I find it much easier to read at a glance. You can change the time period. I think it may be exactly what you may be looking for. I THINK it may have originally been done by one of the guys on here?

Sorry for the VERY LATE RESPONSE!

You asked how I use it - I have incorporated it into a study that defines a stock's movement strength using a variety of measurements that include trend, momentum, relative strength (SPX), Overbought/Oversold and Accumulation/Distribution.

Here is the complete code:

Code:

# RelativeStrength_MultiTimeFrame
#
#
# 04.15.20    Version 1   RmS59

# This indicator calculates the Relative Strength of the underlying security to an alternate (SPX default)
# Allows user to select Aggregation Period for calculation
