From my perspective this can probably be narrowed down to two main reasons:
1. ease of mind -- entering and re-entering ALL the time will be more exhausting than just re-entering when we're actually risking a loss
2. trade location -- perhaps not as valid, depending on the circumstances; but your first entry might have better odds due to where you actually are in the bigger picture
I'm struggling to follow your conversation here. I wasn't in chat so obviously I'm missing some context. If I'm understanding correctly Niko is saying that if the reasons to scratch are valid with 1 point profit those same reasons should apply at any point along the profit journey.
If my understanding is correct then I believe it is a false comparison. When you scratch with a 1 point profit its because you were trying to buy or sell at a decision point. If you aren't propelled as expected and the price action looks dull then scratching allows you to take a fresh look at the market. You are on the sidelines and not strongly invested in the market.
If on the other hand you are 20 points into profit then your understanding of buying and selling was correct. Here a market going dull isn't enough to change our opinion of the market and we should make he market prove that something has changed. Until the last swing low is taken out nothing has changed.
I'm curious if DBP will comment on this?
