I get the SPY overlaid on my results when i apply the following. The problem is the values can have very different magnitudes. Does anybody know how to normalize them to the same Y-axis scale?

* Note - I just randomly chose a couple stocks to show the diffrences

Fetcher[
symlist(prgo,lo)
set{spy,ind(spy,close)}
draw spy on plot close
]



On a side note, if I replace the above with: set{spy,ind(^spy,close)} SF adjusts the closing value of spy to 51.21? I did that by accident switching between spy and ^spx. Strange?

Fetcher[
symlist(prgo,lo)
set{spy,ind(^spy,close)}
draw spy on plot close
]



Thanks for any suggestions! Justin

Concerning your side-note, as indicated previously StockFetcher does not support the index symbol "^SPY" (we do support the ETF "SPY".) Since ^SPY does not exist, it appears the plot you are seeing is from the first stock in the list, "A".

Fetcher[symlist(A)
set{spy,ind(^spy,close)}
draw spy on plot close
]



Hope that helps!

That last thing had puzzled me as well.

believe TRO uses 60 days to normalize:

Fetcher[
sp500

draw ind(spy,close)

set{x, indposition(close,60) * 100}
set{spy1, ind(spy,close) }
set{spy2, indposition(spy1,60) * 100}
draw x on plot spy2

set{c, spy2 - x}
draw c line at 0
]

Thanks for the response Four. I decided to breakdown my normalization step by step and display the results thru add column to find out why I kept getting syntax err. As it turns out the normalization is not the problem, it is that stockfetcher doesn't know what/how to display the results on the main plot. Short of being able to code for the chart display itself, what I want to do can't be done. Its a pity because all the other charting programs I use can easily overlay an index for comparison normalized to the underlying's range.

Since I trade relative strength/weakness and stay with the trend 90% of the time, this feature is very important/convenient as I flip thru charts. Currently I just narrow my results with stockfetcher and then export the results and view them in another charting program.

Thanks again and good trading!
Justin
