When I started trading full time 6 years ago, one of the systems that I could trade successfully was the Opening Range Breakout. But trading that did not need much screen time, and I did not have anything to do the rest of the time. So, I decided to try out other systems - I had the idea that a day trader needed to be more active, and attempt to capture all the significant moves of the day. You can see the number of trading diary threads that I started on traderji, mostly posting live trades day after day, month after month, year after year.
Now, I am back to trading a boring method, similar to the Opening Range Breakout. I am doing much better. I am tracking about 40 Stock Futures for day trading everyday. I don't track manually. I depend on the NSE market reports to choose the stock to trade for the day. It's just a dull daily routine. Over half the days, I take only 1 trade. Since I am not trading actively for most of the trading day, I do something else to keep me from getting bored, Like browsing, reading a book or watching tv, sometimes gardening or cooking. Rarely, if a new trading system interests me, I experiment with it, but with only one lot.
Finally, you have to find the solution to your problem yourself. But getting frustrated, or being unable to deal with boredom is not going to help at all. Get over this phase asap.
Step 1: Get a system with positive expectancy, preferably one that has a higher win rate. Once the money starts coming, it will compensate for the boredom to a large extent.
