You haven’t had a great deal of response yet to your question, and I believe that may be because you have not yet given us much background to go on.
Did you mean that you have been in banking for 30 years or that you left banking 30 years ago? Either way, I can fully understand that you could have been in banking for years without any dealing with forex at all. I also started my working life in retail banking in the UK and only dealt with private retail clients at that time. Foreign exchange was only an occasional side issue linked to certain core transactions and a far cry from forex trading. Only later did I move on to corporate and international banking and become involved in foreign exchange.
If you have had limited experience so far with FX trading then I can imagine that you feel you have a lot to learn and I think you are wise to start with differentiating between the technical and fundamental approach to trading.
As you know, trading forex involves taking positions in a currency pair i.e. a position involves two currencies each with its own set of factors, where one is stronger relative to the other…
Fundamental traders will study all the underlying factors affecting the movements of these two currencies. This includes the state of the economies, central bank monetary and fiscal policies, supply/demand factors, industrial trends, current sentiment, etc. From all these they will form a “barometer reading” of which way the exchange rate between these two currencies is likely to move and take a position accordingly.
Technical traders take one step back from all this. They are only (or mainly) interested in observing and analysing the price movement itself. Their argument is that whatever the fundamental factors are, and whatever the fundamentalists may think, the majority view will always be reflected in the movement of the price - and we are only interested in what the majority of active market participants are actually doing, If we can determine that through analysing price movements with technical tools then we are in a good position to decide when, where, and for how long, we wish to join that movement or even when to trade against it.
But in order to delve into this any further you really need to provide us with some more background of what you know/don’t know, what are your objectives and what kind of trading you are looking to do.
I know this is very vague at this stage, but I hope it encourages you to tell more about plans?
