(Please note that this strategy has expired and is for learning purposes only.)
This is a high-frequency trading strategy on the OKCoin bitcoin trading platform. Running from June 2016, to mid-January 2017, this strategy successfully accumulated the initial investment of 6,000 yuan to 250,000 yuan. Due to the recent high-pressure policy of the central bank on Bitcoin, all major platforms have stopped allocating funds and began to collect transaction fees. This strategy has actually failed, but still a good lesson for a trend strategy design.
This strategy is based on two main ideas:
Trend principle: When the price fluctuates in a trend, the order is followed up in time, that is, chasing the price no matter it raises or falls.
Balance principle: When the opened position deviates from 50%, the small order is released to make the position gradually return to 50%, preventing the reversal of the end of the trend and causing the retreat, that is, take the profit in time.
This strategy requires a balanced position, ie (funds money + financing money = financing coin), so that when the position is 50%, the net assets do not fluctuate with the price, and also ensure that both the ups and downs of the trend fluctuations are earned.
