Before you start intraday oil trading:
Watch out for strong trends
First of all, you should note that in the case of strong uptrends, it is risky to speculate on the previous day's high on a decline in the price of oil. The same is true when there are strong downtrends, where, on the other hand, it is risky to speculate long at a touch of the previous day's support. You should therefore preferably trade those trades that are in the direction of the trend.
Less is sometimes more
In the article, we used supports and resistances based on the high and low of the previous days. Of course, other options can be used, such as the high and low of the previous week, the previous month, pivots, Fibonacci levels, etc. The problem is that if there are too many of these supports and resistances, then ultimately the trader may feel overstimulated. Less is therefore sometimes more.
Follow the fundamentals
Because oil can be very volatile when news is published, you should always check the calendar for that trading day. In particular, major economic news and/or information on oil inventories, etc. have a great potential to move the price of oil significantly within a few minutes or hours.
This method is not for complete beginners
Finally, we would like to make a note of the psychology of intraday trading. As you have noticed, the signals according to the established rules did not occur to us every day, but they occur irregularly. This tends to be a severe test of a trader's psychological resilience. On the one hand, the trader wants to trade every day, on the other hand, the expected signal may not arise on a given day.
The fact that the signal occurs on the day the trader expects it and at the price level is essentially a coincidence. This can be partially addressed by having, for example, two intraday strategies that the trader combines. In any case, intraday trading is one of the more challenging styles and therefore this trading method is not for complete beginners.
