I'm sort of in a similar situation, trading in Vietnam and with the market opening at 9.30pm local time and needing to be up for work before 6am every day and therefore needing to get to bed, I really don't want to trade beyond the first 40 minutes. At the same time this rather suits me! Similar to above, I like the pace of the open, you'll find several set ups for certain strategies in the first 40 mins.
My trading journey: I began to paper trade low float penny stocks back in July 2020. I wasn't very good at it! They are very volatile. I moved to mid-caps in November and took out a BBT lifetime membership. This has been much better, mid-caps are just slightly less volatile and a little more reliable. My big issue now is discipline, and learning to wait for a set up before trading. I am making progress.
I've tried to trade 1 minute ORBs, and have had mixed results. I don't agree you should be watching 6 x time frames per stock, especially not in the first 30 mins of the market. On. DAS Trader I use a 6-ticker watchlist of 1 minute charts built with the help of Carlos and Brian (Brian especially since he'll be trading the open), and then I've got a main tab where I place trades which uses a 1 min, a 5 min and a daily. But yes, 1 min ORBs are difficult to trade. It's partly the mentality - you're so keen to find this setup, you've got to make decisions so fast, and often you'll end up getting a really crappy entry chasing a stock that looks like an ORB but is already extended. Andrew is superb at it - and with practice and experience, they will become easier to trade. But for now I've stepped back from 1 minute ORBs.
Recently I've had more success trading reversals (and 4 green days last week, a first for me!). I've noticed most days at least one of the stocks on my watch list will flush at the open and sell off strongly for 2 to 5 minutes, first as profit taking creates selling pressure and then as shorts step in looking for their own ORBreakdowns. I don't need loads of time frames to see this happen - 1 minute charts work fine. What goes down must come up: these stocks become extended and find a bottom. Shorts cover, longs step in, and you hit a reversal. If you can find a way to keep stops tight you'll get excellent R:R.
Another strategy I trade is a VWAP break, usually long biased. It works best on stocks green for the day, but which sold off on the open. It also works well for stocks where you missed your reversal entry. They'll come back to VWAP, and often pause at VWAP as people begin to sell positions. One of two things happen here: either it rejects VWAP and sells off again, in which case I don't enter. Or it holds VWAP and continues on up, in which case you can get an entry with a good tight stop just back below VWAP.
I hope this is useful! Good luck and stay in touch, sounds like we're in similar boats!
