Global indices strength gauge (Indexed)

Indexed Cross-sectional analysis over different tickers. The user can also change the tickerid so you can make another kind of cross-section analysis.

How the indexing work:
For each ticker, we obtain an indexed value (base on the band) which gauge the relative strength of each global index.

How to read the value :
The value is based on the location from the band.
1 : price is reached its level 1 upper band.
-1 : price is reached its level 1 lower band.
Exceed the boundary: more likely there is a drift on that direction for that moment.
