Does this indicator nail tops and bottoms of the market?
No, it does not. There is no magic here. The indicator reacts to tops and bottoms which meet certain price patterns. Are you completely sure it does not repaint or cheat?
Yes, the indicator does not repaint or cheat in any way. In the video there is a visual backtest, in which you can see that signals appear as soon as the last bar of the formation closes. Past signals are never hidden in any way. Losing trades are highlighted.
Should I close my trades on opposite signals?
By the time an opposite signal has taken place, it is already late to cash out the previous trade. Every trade must be managed and closed before the next one takes place. This is not an always-in-the-market indicator.
I don't do intraday trading. Can this indicator be useful?
Absolutely yes. It works very well on H4, daily or weekly charts.
I get a lot of signals when I load the indicator into very small timeframes like M1 and M5, and the spread does not allow me to earn a decent profit from them. What can I do?
You can switch to a bigger timeframe in which the spread does not kill the payoff, or you can increase the MinRange parameter in order to decrease the signals density. Trading more does not necessarily mean earning more money, you have to find the best balance between the expected profit from your trades and the spread payed for each trade. How can I avoid losing signals?
Losing signals are simply part of the game, however they mostly take place when a trade has been triggered by a sudden spike bar which depletes the price movement or against double tops or bottoms. If you can avoid spike bars, you will do just fine.
Which is the best confirmation?
There is none by default. Confirmation of trades is up to you.
