Is it possible to know when price will move rapidly?

I read bill williams book trading chaos and the other one i think something on how to manage your wealth i forgot the exact title but the book is pretty famous.

Anyway my problem with both these books is that they describe the problem but don't give any solution to it.

Like they will say price ranges most of the time but it will trend shoot up or down sometimes but we don't when just want to tell you that.

Here's my question how do you know when market will range on a pair? I understand each pair is different so you have to use a different form of analysis.

Each instrument is different but you can and should use a standard form of analysis.

If price is approaching a significant Support or Resistance, Price may reverse in a rapid fashion. Another time is when "big money" or
HFT's are playing the stops, Price will make a rapid surprising reversal and proceeds to take out the nearby stops. At least that is my
observations.

Google average trading range by session for the currency pairs you wish to trade.
You'll easily understand when more volume enters the market.

When does price move rapidly? Watch the charts, alongside a live (non-delayed) newsfeed. You'll soon see that unexpected news makes price move rapidly.

Other than that, it depends on which timeframe you're watching. On a 1-minute chart, price can appear to move rapidly when a large order hits the market.

The inverse applies to your question regarding price ranging.

Wait for the NFP if u want to see rapid moves ahahah

Apart from on rare occasions of high-impact fundamental announcements (which can sometimes be both dangerous and difficult to trade even if you get the direction right), it isn't possible to know with certainty when volatility will suddenly and dramatically increase, but fortunately it isn't necessary, either.

Some times (e.g. after a period of tight congestion in an otherwise relatively volatile and highly liquid market) are significantly more likely than others: these things (like most of forex-trading) are all relative probability functions.
