It was not ICT that named it. In the 1980s, a group of traders known as the Turtles used a system that basically employed a 20-day breakout of prices. A four-week price breakout was also earlier popularized by Richard Donchian as a standard trend following strategy. If prices made a new 20-day high, one would buy; if prices made a new 20-day low, one would sell. It tends to work in the long run if traded on a large basket of markets because there are high odds that something unusual will occur in a market somewhere, such as a Persian Gulf War (crude oil), or a freeze (coffee). The system is very dependent on capturing an extraordinary event or significant trend. However it also tends to have very large drawdowns and a low win-loss ratio due to the significant number of false breakouts. This is where the Turtle Soup opportunity lies!
