Fibonacci harmonic patterns are commonly used by traders to identify buy and sell signals. They're statistical patterns with many variations that have been profitable in the long-run since the early 2000's.
Here's a quick overview of a Fibonacci Bat pattern:
Here's a market example of a Dash/USD trade using a 3 hour chart:
Risk/Reward Ratio
Risking: $305 - $280 = $25
Potential Profit: $350 - $305 = $45 or 14.75%
Risk/Reward Ratio: $45/$25 = 1.8
To stay profitable in the long-run, make sure that you're risking at least as much as your potential return, which means maintaining a risk/reward ratio of at least 1.
Happy trading!
