Skills can help when trading for weeks or months, but intraday trading is not subject to technical analysis! I'm talking about it because I was losing my money trading intraday! 
for me, daily trading is like gambling which only relies on luck (without analysis and skill).. I still remember what someone said "TRADING = 20% buy or sell & 80% WAIT"You are right, in gambling like sports betting you will need to have to analyze every match and place your bet upon your analysis was done. Just kinda sort of trading, you also need technical and fundamental analysis in predicting which team will win. Not only sports betting required skill in gambling, but it is also in card games like poker and tong-its.
That's right.. Poker, sports betting (soccer, boxing, basketball, and racing) is the same as Profesional Trading that requires technical analysis..
