This is a useful indicator but I found that it sometime produce false signals..
Here’s the steps to reproduce:
- Install indicators, use default values
- Once an arrow occurs, switch to different time frame.
- If the arrow stays, then the signal is true, if the arrow disappears that means the the signal was false.
- This is especially true when back testing after on it for some time..
Is there a way to fix this?
Thanks.. BC

The same problem in the logic, as I reported for the BB_Stop signal.

Hey My friend
could you tell me how to configure this indicator’s parameters?
thank you
best regards

Hello Nikolay,
Have you turned the signal into a strategy? If not would you please at your convenience create a strategy for this signal.
It will be much appreciated.
Regards,
Richard

Hello Nikolay,
I had the ALTR Sirnal open a LONG trade today. Is that possible?
I will continue to monitor.

Hello dear, is it possible to have a Multi Time Frame indicator (perhaps up to 5 different time frames) for this indicator? Thanks.

In the next release of the platform you can choose the time frame for any indicator, right in the indicator properties, on the source tab. Please wait a bit. The beta version will be published on this site soon. Watch for updates.

The indicator was revised and updated.

Reymondpolanco · Sun Sep 02, 2018 12:10 pm
Can you make this like an strategy too.
With this parameters:
when a buy signal open a buy trade and close all sell trades when a sell signal open a sell trade and close all buy trades
