总收益率与平均胜率以及每次交易的平均收益率之间存在这样的关系: ΣP=[(W% x P1%)-(L% x P2%)] x N ΣP为总收益率, W 为平均胜率, P1为平均盈利率, L为平均赔率,P2为平均亏损率,N 为交易次数。 上述公式成立有一个前提条件:必须有足够多的交易次数,一般来说N>=30次。 两个例子: A交易系统:W=60%, P1=5%, L=40%, P2=5% ΣP=(W x P1 – L x P2)x 30=(0.6 x 0.05 – 0.4 x 0.05)x 30= 30% B交易系统:W=30%, P1=21%, L=70%, P2=7% ΣP=(W x P1 – L x P2)x 30=(0.3 x 0.21 – 0.7 x 0.07)x 30= 42% 两个系统30次交易后的总收益率都是正的,说明都是赚钱的交易系统; 能够赚钱的交易系统,都需要坚守,需要交易次数达到一定数量后才能体现稳定盈利。不需要在意单独某一单止损还是止盈的原因,只要做单次数够了就能盈利,共勉拜托,如果连交易稳定盈利的原理都不懂就注定只能亏钱,看懂以上的小伙伴再上车
