I have no experience in this style of trading but understand what you are trying to do. It is another method of avoiding the high daily volatility while ensuring that you are invested in the markets.
You will need to use leverage to get bigger profits, this means cfds or options US stocks)
Do as much paper trading as you can to fully understand what can go wrong. Use TA to time your entries into spreads that you have identified.
Work out the right risk/reward for your W%.
Exit trades that start losing even if it is one of a pair. Replace it with another stock same sector.
Short a poor stock against its sector (EFTs) if you have strong ideas about one stock.
I have said it before, there are unlimited opportunities out there every day for you. Get into them.
