首先感谢各位大佬的分享，受益良多，特别鸣谢大树“My05613828” 大佬，从大佬那找了不少的参考资源
我写了一个MT5的EA代码，源码附上，请各位前辈指正（帮忙看看逻辑是否有问题，回测就爆仓）：
一、输入参数
交易手数
止盈差值
止损差值
二、交易逻辑
获取当前品种当前周期的布林上中下轨的价格信息
开仓条件=0
如果价格低于了下轨，开仓条件=1
如果价格超过了上轨，开仓条件=2
获取当前订单数
如果订单数为0，开仓条件=1，买入价格大于等于下轨价格，做多单，按输入差值设置止盈、止损
如果订单数为0，开仓条件=2，卖出价格小于等于上轨价格，做空单，按输入差值设置止盈、止损
如果订单数为1，手中持有多单，买入价格触及中轨，平仓
如果订单数为1，手中持有空单，卖出价格触及中轨，平仓
