正量能:MA(100*(L- LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N)),3),COLORYELLOW,LINETHICK1;

负量能:MA(-100*(L- LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N)),3),COLORWHITE,LINETHICK1;

正趋势: EMA(100*(L-LLV(LOW,P))/(HHV(HIGH,P)-LLV(LOW,P)),K)/2,COLORRED;

负趋势: EMA(-100*(L-LLV(LOW,P))/(HHV(HIGH,P)-LLV(LOW,P)),K)/2,COLORGREEN;
