在网上朋友转过来的指标主图，觉得不错！现拿出来与大家分享！
{不过高抛低吸}
HH:=HHV(H,20);
LL:=LLV(L,20);
MID:=(HH+LL)/2;
UPPER:=MID+(HH-LL)*0.2;
LOWER:=MID-(HH-LL)*0.2;
BUY_CONDITION:=C<LOWER AND REF(C,1)>=REF(LOWER,1);
SELL_CONDITION:=C>UPPER AND REF(C,1)<=REF(UPPER,1);
DRAWICON(BUY_CONDITION, L*0.98, 1);
DRAWICON(SELL_CONDITION, H*1.02, 2);
