At the end of the sentence you mentioned DCA as a step to close the post and I think this is very confusing to understand because of some of the trading strategies you are trying to match with DCA, because usually DCA is only used in investing not in trading. Trading does not fully talk about alignment with trading style and goals, it is possible that along the way the strategy has to be changed and we have to adjust to the ongoing market conditions.
Im selling an iPhone here and asked for a loan so I can start my trading journey (hopefully soon) but the trading strategies got me thinking. How well do you define that for yourself? Or think about it? write down or on the wall or whatever?
The reason is obvious that lending money to go through trading is out of the question, let alone involving beginners in it who have no experience with trading itself. Defining or thinking about anything related to trading is not easy and you need to study it first to understand it.
