DCLOSE_VAR：取前一根K线的ZIG转向值，ZIG函数参数为3和0.00001，表示基于收盘价，以0.001%的幅度判断转向。
DOPEN_VAR：取最近一次ZIG转向发生时的开盘价。判断逻辑是当ZIG转向值不等于前一根K线的ZIG转向值时，记录当时的开盘价。
DHIGH_VAR：计算从最近一次ZIG转向发生到当前K线期间的最高价。
DLOW_VAR：计算从最近一次ZIG转向发生到当前K线期间的最低价。
DVOL_VAR：计算从最近一次ZIG转向发生到当前K线期间的成交量总和，结果乘以100。
DCLOSE_VAR:REF(ZIG(3,0.00001),1);
DOPEN_VAR:REF((ZIG(3,0.00001)<>REF(ZIG(3,0.00001),1))*OPEN, BARSLAST(ZIG(3,0.00001)<>REF(ZIG(3,0.00001),1)));
DHIGH_VAR:HHV(HIGH, BARSLAST(ZIG(3,0.00001)<>REF(ZIG(3,0.00001),1))+1);
DLOW_VAR:LLV(LOW, BARSLAST(ZIG(3,0.00001)<>REF(ZIG(3,0.00001),1))+1);
DVOL_VAR:SUM(VOL, BARSLAST(ZIG(3,0.00001)<>REF(ZIG(3,0.00001),1))+1)*100;
