this is exactly why i like to sell within 3, 1hr candles. even if hits tp, honestly i feel not worth, if so sure about the trade, get the best entry possible and reduce sl for higher RR win. i really don't believe in swing trading, unless you caught the trade from the beginning on a higher time frame.
too many times before more lose then win, because i didnt'take my winners.
3 candle rule for me only applies when there is the big dump, not when consolidating.
if so sure it will keep going down, just find another entry when it goes down. but i think taking the winners first is very important.
also don't day trade and short a support or long a major resistance, esp on higher timeframe. 3RR should be your main sl at profit after you reach more then 3RR eg, you in 5RR winning, sl should be there.
think these tips are something i learnt and helped me alot, hope it helps others, this is more for day trading, not for swing/ investing/ scalping
