How do you trade then? Order flow only? I used to do some of that some time ago but I feel like the order flow changed a lot since algorithms became a big part of it. Much less readable/usable for me.
My thought is that I have them on to have in the background if something really bad happens or to pick up on some little tid bit. An example being TSLA, I don't remember how long ago now, but on CNBC someone mentioned that Elon needed the price to be up to x dollars to qualify for a huge payout. I bought some on this feeling comfortable that Elon would magically meet sales numbers to push the stock. It slowly moved fromm $180 at the time to over $300 then they had earnings and it popped to $600, and the following Monday it hit $900. You don't have to watch it, just listen in background. I have had a couple of those over the years. One other was a strike price on a SPY put that was being accumulated. I picked up a small position and it sat in a .55- .65 range for quite awhile and then the markets tanked and it ran over $30. Sadly I had worked out of the position, first covering my cost, then taking some more at $10, $15 and $25.
One of the biggest mistake many traders make is having too many indicators. Adding couple of indicators to price action works great.
I wanted a moving average that didn't lag, but found that those which were supposed to serve this function, like the Hull Moving Average and the Zero Lag Moving Average, were inadequate. I therefore set about learning enough about coding to design the indicators I envisioned for myself, if and when then did not exist. For example, this page from my book illustrates the difference between the two above-mentioned moving averages, and my own "instantaneous moving average."
