Depending on your strategy you might require some further confirmation such as a pattern or . That's what I require to take this on, there might even be some on the lower 15m time frame. Trade your plan guys and if you don't have a plan, best not to trade, not even on a demo account, it's wasting your time.
Feel free to message me with any questions and I'll try my best to get back to you.
