FX Futures Expiry Date Effect on Forex

Hi - I know some people love extra volatility but my system requires average market conditions. Because of this I am trying to make sure I find the times when NOT to trade. My question is how much impact the fx futures market price has on the forex market spot price. I know the futures markets can go a bit crazy on expiry date, does this have a knock on effect to the forex market spot price volatility/unusual/whipsaw movement on these dates or not? My interest is in the Majors.

Thanks in advance for any assistance.

I think in the currency markets, more than futures, options tend to influence prices when nearing their expiry times, monthly/quarterly/half yearly tend to hold greater significance.

agreed, plus the main price point options which is where the bigger volumes sit

Futures are irrelevant, as it's a very small mkt. Options, especially the various exotic matter a lot. There's also other effects like the WMR and month-end fixings. Those are all significant.
