Well really there is no foreseeing is there, only once price crosses a trend line and sma on a higher time frame then the lower time frame is in that trend. trade accordingly then long or short.
Then there are reversal signals a whole other discussion
OK. Let's have a hypothetical example. Daily bar closes below rising trendline, then some days later it closes below 70 SMA and you go short, where is the stop and where is the target?
