Trading can be easily compared with fishing. Both have a bit of uncertainty about the result: whether it will be significant or not. Moreover, the factor of success is also quite important here, as well as initial investments into fishing rods, equipment, and bait for fishes.
If you have a long look at the Parabolic SAR chart, then you may notice that its form reminds a fishing rod.
Picture 1. Japanese candlestick chart of EURUSD with the period of 1 minute and the Parabolic SAR indicator with a standard setup.
Such a strategy implies both signals "up" and "down".
Trade "up"
When the fishing rod touches a "float" from upside, then we start pulling up to get the fish out, and invest "upper".
Picture 2. Japanese candlestick chart of EURUSD with the period of 1 minute and the Parabolic SAR indicator with a standard setup of "upper" signal.
In picture 2 we can see that touching or crossing the Parabolic SAR chart and candle from down to up is a trigger for an "upper" signal.
Trade "down"
When the fishing rod touches a "float" from downside, then you can imagine that the rod is ready to throw and it is time for investing "down". The further chart will be an artistic continuation reflecting your fishing line descending to the water.
Picture 3. Japanese candlestick chart of EURUSD with the period of 1 minute and the Parabolic SAR indicator with a standard setup of "lower" signal.
In picture 3 we can see that touching or crossing the Parabolic SAR chart and candle from up to down is a trigger for a "lower" signal.
Recommendations about using the strategy
The best market state to use: the strategy shows itself very good as on a sideways trend, as during the periods of a pronounced trend.
Recommended expiration time to set up: 1 minute
Have good fishing!
