Palladium/Platinum crossover trigger to go LONG

Platinum and palladium are both used in automotive catalytic converter manufacture. Palladium is dropping to the point where it may well cross over the price of palladium.
At this point catalytic converter manufacturers would want to switch from Platinum to Palladium and/or hedge Palladium to protect against future price rise.
Watch for the crossover and then switch to shorter timescale tools to reinforce the buy signal.
This is a long term investment opportunity rather than a quick in and out trade.
As ever, this is opinion only. Do your own research. Never place what you cannot afford to lose.
If you liked this idea please give me a boost.
Good Luck
