Technical analysis including luck is the best way to earn prpfits, I agree for that way not to be greedy, taking small prpfits for the daily trade very effective is enough.
A small profits can get for daily trade job 10 to 15 percent interest, add their a weekly earning I think from small to become huge.
Definitely more analysis than luck but we can't say luck has no play in this neither. Think of it this way do you need luck or skill to be a good actor? Now you can be the luckiest man on earth but if you have no talent than you can't be a movie star, you can play here and there but in the end you will not be making it very long.
However, if you are a great actor with no luck you can actually grind your way into the business, play here and there and people will love you and than you will play in bigger things, you may never be a blockbuster success but you will at least make your money that way until you retire. Hence same with analysis, if you are a good analysis of sorts than you can eventually make money, if you are however lucky you can make profit just once or twice but you can't get lucky forever.
