Through the years for my own trading I have backtested and used optimizing softwares to find best EMA's and then I will look at 4 above and below level of both EMA's and always makes for great crossovers to turn into losing for me. So just using crossovers I will never use for entries. I been using 18sma since start of my career in trading, slope and price Thrust has worked best for me to define trend. I don't like stochastics much, again never tested well enough for me using, have used RSI a number of ways to give signals and different approaches of retracement, I don't care much for breakouts after retracement to 18sma, I prefer to enter when knife is falling then to wait for confirmation that it is rebounding. The larger the timeframe, perfect entry not as important as money management of after one enters.
