Will price movement/nature behave the same in the future?

Will price movement/nature behave the same say in the future as it does so now?

I'm sure most of us have had this worry that perhaps the way forex prices behave now will suddenly change and that your current strategy will become void.

I wouldn't say the same, but similarly. There are reoccurring patterns/setups that can be traded over and over. However, price action leading up to those patterns/setups can vary. The imbalance of buying-selling pressure can take on many forms, but I don't think it can ever hide. There will always be clues to look out for on the chart. I'd like to hear what other people think.

Will supply and demand behave the same today as they will in the future?
Did supply and demand behave the the same way it did 100 years ago as opposed to today?
What's the core difference between bitcoin, oil, indices, stocks, forex, housing prices, elspot, coffee, beans, sugar, metals? There are none. They're all a result of supply and demand. Unless there's a change into how humans react to supply and demand, it has, is and will behave like it's supposed to.

i think about something like this sometimes. what if the market changes and my profitable strategy stops working ? but if my profitable strategy stopped working because of the market changing, was it even a profitable strategy in the first place ? whats a profitable strategy, something that wins everytime or something that win for a lonnng time even if at one point it blows ?

How do you measure a good strategy? any strategy can work on a short period of time, the longer the strategy work the better it is.
I suggest not to count only on your strategy, specially if you are only using technical indicators and its always good to try new things.
Can you elaborate about your strategy?
