Finally i can reply your questions
At first i draw in every timeframe trendlines. After that i look for possible trades, short or long. For example i find a possible long access in the h 4 chart, but i see that we have a down trend in daily chart. So that is a resistance. i still take the access in the h4 chart but my TP must be on or under the daily trendline. But if i have a trendline of smaller time on the way (trendline of H1 or smaller) so i dont regard this resistance, because im on the major time frame.
To your next question: Your SL should be above the C point.
I hope i could help you
If not ask me again..
regards
