What Is SharkFin?

When trading cryptocurrencies, it is of utmost importance for traders to lower their risk and secure profit. Although not limited to cryptocurrencies, the Sharkfin market movement is one of the studied patterns for achieving these goals. The strategy, as the name implies, is a “look-like” of shark fins and it is identified using some trading indicators.

What is Sharkfin?

Technically, a sharkfin is a market movement that occurs when the Relative Strength Index (RSI) extends out of the Bollinger bands on the Traders Dynamic Index (TDI). These extensions create market patterns shaped like shark fins on the Bollinger bands.

A Sharkfin can also be referred to as a trading method implemented following the prediction of future sharkfin market patterns.

Bollinger Bands

Bollinger bands are oscillating lines that appear at 2 Standard deviations above and below a market’s moving average over 20 days. Bollinger bands are formerly called trading bands. It was developed by John Bollinger in the 1980s and trademarked Bollinger bands in 2011.

Relative Strength Index

The RSI is an indicator that displays the speed and size (momentum) of a stock’s price changes. It indicates the rate at which a stock is being bought or sold.

Traders Dynamic Index (TDI)

The Traders Dynamic Index (TDI) Pro indicator is a 3-in-1 market indicator that reveals predictable Entry & Exit Points of trade. It was invented in 2005 by Dean Malone, who allegedly made millions using it to trade.

As a 3-in-1 market indicator, the TDI Pro indicator shows the trend direction, momentum, and market volatility of a currency in a market. It is designed for use in the MetaTrader 4.0 platform.

Sharkfin market movements can only be effectively detected using the TDI Pro indicator.

How to Identify a Sharkfin

Sharkfin: The Market Movement

The Sharkfin market movement occurs when the RSI moves past the Bollinger bands creating a Sharkfin-above-water movement graphically. Sharkfins happen downwards or upwards along with the Bollinger bands.

This analysis is carried out on the Traders Dynamic Index (TDI), where the Bolinger bands are visible and easy to see in a graphical presentation. A one-hour time frame is usually used for this analysis.

A sharkfin typically happens at the levels of 25 and 70. When the RSI breaks through the Bolinger bands and reaches a level of 75 or greater, this is called a bearish Sharkfin. You sell during a bearish sharkfin.

Where the RSI falls to 30-25 and below, it’s the time to buy. This trade follows the basic rule of commerce: buy low, sell high.

Sharkfins at the top indicate that a currency has been “overstretched” (overbought) and will likely start being sold off. When Sharkfin is at the bottom, it indicates that the currency has been oversold and will soon start getting high demand because of its low price.

As a general rule, when looking to trade with Sharkfins, you buy when the RSI of the stock is at 30 and below and sell when the RSI is at 70 or above.

Summarily, when the RSI extends close to the Bolinger bands, there could be a possible Sharkfin forming.

Sharkfin: The Trading Method

After predicting a bearish Sharkfin you want to trade on, the process of selling at this point is called a Sharkfin. Buying low using the downward Sharkfin movement is also referred to as Sharkfin.

The entire process of identifying and trading a Sharkfin (market movement) could also be referred to as Sharkfin (trading method).

To trade a Sharkfin, switch from a one-hour to a 5 minutes time frame so you can see the point you want to enter from. Here, you navigate to the Long position to choose a Stop Loss. A Stop Loss is a period you want to ride the RSI for with hope for another upward Sharkfin giving you a profit.

When you want to sell, navigate to the Short position to choose a TP.

Confluence in Sharkfin Trading

Sharkfin trades have a high probability of succeeding. Nevertheless, it is also advisable to make a sharkfin trade only when there is confluence in the market. Confluence helps you avoid anticipating and trading fake Sharkfins.

Confluence is when two or more factors point towards a high probability of a good time to buy or sell. The purpose of using a confluence is to get greater accuracy in the market predictions that influence your buy/sell move.

You can achieve confluence by combining two or more results from technical analysis and other many trading techniques.

Working with confluence reduces your loss time to almost zero and increases your earning ratio.

Examples of Confluences to Consider

  1. Moving average touch. E.g. 8 Moving Average, 50 Moving Average, 200 Moving Average, 800 Moving Average, etc.
  2. Trendline
  3. Trendline retest
  4. Major areas of support
  5. Major areas of resistance
  6. Key Fibonacci level
  7. Higher time frames of significant moving averages
  8. Higher time frames of critical Bollinger bands touch points.
