It can be used in a communication letter without l2 reference. I don't know if it's what you want, but the formula was downloaded from the internet.

ZLCM:=EMA(WINNER(CLOSE)*7，3)； Main chip estimation

SHCM:= EMA((WINNER(CLOSE * 1. 1)-WINNER(CLOSE * 0.9))* 8，3)； {Retail Chip Estimation}

ZSHTL:= SHCM/(ZLCM+SHCM)* 10； {Retail investors lock the chip ratio}

ZCMZL:=MA(ZLCM+SHCM， 13)； {Total market chips}

ZZNTS:= bars last(ZSHTL & lt； 9? And then what? REF(ZSHTL， 1)>9); {the day of herding cattle}

ZSHJJ:=EMA(ZSHTL，89)；

Midline strength: if (zlcm/(zlcm+shcm) * 20-4 > 0,2 * (zlcm/(zlcm+shcm) * 20-4), 0), COLORRED, LINETHICK2{ master chip ratio}

ZZLJJ:=EMA (strong midline, 89);

ZJLRQD:=IF(INTPART (centerline strength-zzljj) > 0, INTPART (centerline strength -ZZLJJ)- 1, 0); {Intensity of capital inflow}

Short-term strength: IF(ZJLRQD & gt；; 0? And then what? C & gtREF(C， 1)，ZJLRQD* 1.5，0)，LINETHICK3，COLORMAGENTA

Short-term strength minus yesterday: short-term strength -REF (short-term strength, 1), LINETHICK0.
