Hello Oppie,
DeMark trend lines (aka Mouteki for ForexFactory members

) are very popular even for the big dogs, so it makes sense to use them on a regular basis. They work!
Your EUR/USD, GBP/USD DeMark trend lines are not drawn correctly.
Simplest way for me to explain. (DeMark) trend lines are useful to spot the trend and to correctly identify trend or side-ways trading breakouts.
Nevertheless your entries were good, and the two trades ended up in profit. That's the result of another pattern - trend continuation or trend acceleration - when the price brakes through the lower trend line of it's downward trending channel.
Happy trading...don't forget to add price action to your trading knowledge.
