This strategy calculates the last highest price (lastbull) and the last lowest price (lastbear). It then compares the current price with lastbull and lastbear to determine if the price has entered a certain range and thus generates trading signals. It goes long when the price rises over lastbull by a certain percentage, and goes short when the price falls below lastbear by a certain percentage.
The strategy first calculates the last highest price lastbull and the last lowest price lastbear. Then it calculates the change percentage ddl of current price close relative to lastbull, and the change percentage dds relative to lastbear.
When ddl is lower than the configured long signal threshold signallong, a long signal up is generated. When dds is higher than the configured short signal threshold signalshort, a short signal dn is generated.
Upon receiving long signal, it opens long position if the needlong parameter is true. Upon receiving short signal, it opens short position if the needshort parameter is true. The position size capital is calculated from account equity.
It closes long position when price rises after opening long, and closes short position when price falls after opening short.
This strategy combines trend and range analysis. It can catch trends and generate trading signals from range breakouts. Compared to simple trend tracking strategies, it can quickly catch new trend direction after range breakout.
The parameters are highly configurable for different products. The trading time range can be configured to avoid significant events.
There is no stop loss mechanism in this strategy to limit the loss per trade. The position sizing can be impacted heavily by price fluctuation when the trading range is large.
Stop loss can be added to limit the per trade loss. The position sizing algorithm can be customized based on products to stabilize the position size.
This strategy combines trend analysis and range breakout to generate trading signals, which can catch new trends and take advantage of range bound characteristics. The parameters are highly configurable for different products. There is large room for optimization to adapt more complex market environments.
