请高手指点，如何画趋势线？

月线有可能下行考验3058点的支撑力度，

周线有望冲击3118点，失败则回试3100点支撑。支撑失败则下探可能下行考验3058点的支撑力度，



日线回试3100点支撑后有望冲击3130~3138点压力。
下周会怎么走呢？？？？？

要看你是什么心态（周期）来画，画线时最好去掉均线。

ainin

周线获得3058点的支撑，有向上突破3118点压制的可能，若失败则再次确认3058点的支撑，若成功则冲击3158点。

日线站稳3086点中位线，有可能成为“希望之星”，明天冲击3118~3128点区域，失败则回探3080.

60分钟线明天将回试3100点的支撑力度。上探3128点的压力。明天收阳的概率大些？？？？？？？？？？？？？？？

厉害！
