Here is a very simple signal that I like and enjoy...
When you see MA200 dropping fast down but prices move above, this is a signal that the next move will be up.
Keep in mind that is recommended to look for multiple signals to support your bias...
One signal can be good/strong but in my opinion is never enough.
Also, make sure to build a plan before you trade.
The signal can tell you about a price jump/drop, but it doesn't tell you what to do after so better prepare.
Namaste.
