DislikedWengOn how's your 10k friend doing?
As for trendline.. Trust your eyes and try to pull a line that connects at least 2 tops/bottoms. For starters, to convince yourself that these lines MAY work, do so on m15/m30 TFs, and see for yourself that they are 'respected' (i.e. At least u shd see signs of hesitation when price gets near the trendline).
