If you don't mind JT, I am going to deconstruct some things in your long post that I think you and others might find useful. As is always the case, this is just my opinion and not fact.
Like most people I wasted an awful lot of time looking for indicators and learning all kinds of TA. I am happy that I have now ditched all of that and now focus on simple price action and mainly support/resistance.
I have found that once you understand the mechanics of how the auction/price discovery process works, TA actually makes a little more sense. The problem with TA is that people interpret TA literally when in fact it is a bit more nuanced.
A lot of TA is also lagging price. This has two effects:
1) You enter a move late but it has an element of 'confirmation' embedded in it.
2) As you offset trade location vs confirmation, you get in at a sh1tier price and therefore limit the profitability of the trade.
I would say on longer timeframes it is meaningful but it isn't anything that is already evident in price alone. On short term timeframes, I doubt whether it provides anything better than a random outcome.
I am certainly aware of the journey ahead. I know it is not going to be easy. On the plus side my cost of living is low (especially for London), my girlfriend has a steady well paid job and I have enough experience to get back into work should I need to. So I am happy with the risk I am going to take.
You will probably need a lot of support from your girlfriend. Have you talked through the reality of this?
The only counsel I will put on the table is this:
The fantasy of trading will burst very, very quickly once you start doing this. It is likely to coincide with a lump of money gone and your head in a bit of a mess. You will need support from your GF. If she is complicit in the fantasy then you will start to attack each other. If you have a strong relationship you will need her support to work through this and this will also take its toll on her too. You really need to look after each other. Both of you should be prepared for some fairly rocky sh1t ahead.
When Pat posted the
it was with really good reason. I think we're both saying the same thing to you - this is going to be far tougher than you anticipated on lots of different levels.
