I would say when you use indicator points 70 and 30 it is far less accurate just because for me and even I have found the last two months or more of these indicators are very problematic when the market has suffered very well Trend, you will have total disappointment because your friend is careful -heart! and this system will be the best for brokers at 15 minutes because in this system when prices touch the bottom line rather than a retreat and this is an opportunity for brokers. Some ways this image shows that the best in the H1 time frame is also because we can see a clear trend in the picture.
