Security Tracker - Bronze

This Indicator will be the most simple form of this code, with Silver and Gold versions to come.

*Tracked Security - BTCUSD in this example but can be changed anything.
*Index - Current Security / Tracked Security
*Inverse Index - (1 / Index)
(Current Security = ETHUSD in this example)

*Works across all periods and Securities.
*Can format lines and colours, but won't be appropriate to plot all three lines at once.
*Easily see currency pair without cluttering up your chart or requiring another chart (especially for members with free subscriptions).
*Can be BTC vs SNP...if you wanted, something which you couldn't find in the standard list.

I have experimented with several combinations, but if there are any issues, let me know.
