The shark trap, or simply the trap, is a trading strategy that is the opposite of the shark trading rules, which exploits the shortcomings of the following trading (especially the shark method) in many false breakouts to profit (making the shark a shark to eat).
In the early 1980s, there was a very famous group of traders called the Seagulls. The legendary market master Richard Dennis, who created the trading legend, came up with this interesting name when training a group of new traders. Richard believed that training traders was actually like raising seagulls in Singapore.
More than two decades later, the beach method is no longer a secret and many people know about it. Still, why are so few people still trading successfully with it? That's because following a trend strategy often requires enduring large and long pullbacks. Many investors or traders don't have enough capital or are willing to stick to these long-term losses.
This is called the "Street Smarts", as opposed to the "Street Smarts" by Linda Wooski and Larry Connolly in their book Street Smarts. The reason most strategies fail to stay profitable is that once many market participants use them, the profitability of these strategies deteriorates. This is the way the market balances those imbalances.
The original rules for trading in the shell were at least a series of trading sessions or longer sessions, with a time span of between a week and a month. Ms. Waski used the shell strategy to make shorter intraday or wave trades, concentrating on the high frequency occurrence of false breakouts. Generally, the 20-day cycle used by the shell method is a breakthrough: breaking the 20-day high is bought, falling the 20-day low is sold.
The strategy features: Supports trend tracking at any level (minutes K, hours K, days K, weeks K, etc.) Supports arbitrary trading pairs (ETH/BTC, BSV/BTC etc.) Support for any exchange Detailed strategy reports (including strategy status, transaction history, etc.) Supports up to 10 customization parameters
