Hey everybody, I have a little problem with my thinkorswim script.

I tweaked the Symbol Relation study from TOS and added a simple moving average to it.

However, SMA is not displayed right after the open - and the higher is the length of SMA - the longer it takes to appear on the chart.

I would really appreciate, if someone could help me with this and fix it....

Thanks..

script:

declare lower;
input price = FundamentalType.CLOSE;
input relationWithSecurity = "VXX";
input length = 9;
input displace = 0;
def price1 = fundamental(price);
def price2 = fundamental(price, relationWithSecurity);
plot Relation = if price2 == 0 then Double.NaN else price2 / price1;
Relation.SetDefaultColor(GetColor(1));
plot SMA = Average(Relation[-displace], length);
SMA.SetDefaultColor(GetColor(5));

On the left side I have SPY chart with SMA(60); on the right SMA(9)

I want SMA to be displayed right off the open - for some reason it does not appear.

Thanks.

P.S.

Each +1 in length of SMA shortens it. I wonder what's the reason for that.

For some reason 5-minute chart gets the longest MA...

There are some gaps in the candles of the premarket VXX "relation" line; each blank space it is restarting the MA length count. The Moving Average is an average of the defined length. If using a length of 9, after the first gap count 9 candles and then the MA starts. With 60, it needs a length of 60 candles to average before the MA line plot starts.

I see.

But then, I get (VXX)/(SPY) in Prophet with any average and it seems to be... fine...?

and why 5 minute chart gets better results than 1 minute?
