@l-andorrà How to buy, how much to pay in USD

@l-andorrà When 5-20 is higher than 50, there is interest. When the interest reaches a certain level, 5 and 20 are crossed and closed to harvest the interest.

@l-andorrà correct

My idea is the 5-day moving average, the 20-day moving average, and the 50-day moving average. When the 5-day moving average crosses the 20-day moving average and the 50-day moving average, open a long order, and when the 5-day moving average crosses the 20-day moving average in a long order, the position will be closed.
The 5-day moving average crosses the 20-day moving average and the 50-day moving average to open a short order, and the 5-day moving average crosses the 20-day moving average to close the short position.
Which generous philanthropist can build a template for me

我的想法是 5均线 20均线 50均线 ，当 5均线 穿过 20均线和50均线 开仓， 当5均线再次穿过20均线 平仓，依次循环。但是 我不知道怎么实现这个想法。
