Apparently on oanda you can trade gold and silver now. The spreads right now are 70 and 300 respectively. Are these decent spreads for them?

I added two models, Model 5 and Model 6. The original 4 models remain. I did not mess with the original code. I simply added two models.
Model 5 uses these fibonacci numbers: 610 987 1597
Model 6 uses these fibonacci numbers: 987 1597 2584
I created this because the Gold/Daily chart in MT4 does not fit into the first 4 risk models. I was almost happy with just the 5th model but a historical look showed an even wider spread on the outer fibs were necessary. Thus, model 6.
Any suggestions which model works best? I think 6 is a good choice but model 5 in a lot of places works well.
