{哥要起涨}a:=(3*close+low+open+high)/6;d1:=(20*a+19*ref(a,1)+18*ref(a,2)+17*ref(a,3)+16*ref(a,4)+15*ref(a,5)+14*ref(a,6)+13*ref(a,7)+12*ref(a,8)+11*ref(a,9)+10*ref(a,10)+9*ref(a,11)+8*ref(a,12)+7*ref(a,13)+6*ref(a,14)+5*ref(a,15)+4*ref(a,16)+3*ref(a,17)+2*ref(a,18)+ref(a,20))/211;d2:=ema(d1,2);d3:=ema(d2,2);k1:=ema(d3,2);哥要起涨:cross(d1,k1);{加速上涨}趋势线:=ema(100*(c-llv(low,34))/(hhv(h,34)-llv(low,34)),3);var1:=ref((low+open+close+high)/4,1);var21:=sma(abs(high-var1),13,1)/sma(min(high-var1,0),10,1);var31:=ema(var21,10);var41:=hhv(high,33);var51:=ema(if(high>=var41,var31,0),3);主力拉高:=if(var51<ref(var51,1),var51,0);出货:=if(var51>ref(var51,1),var51,0);xg:趋势线>80 and (主力拉高 or 出货);{强势选股}趋势线:=ema(100*(c-llv(low,34))/(hhv(h,34)-llv(low,34)),3);xg:filter(every(趋势线>60,6),20);公式一和三用到隐形未来函数“ema”，信号基本可靠。公式二用到未来函数“sma”，需稍加注意。股票公式专家团为你解答，希望能帮到你，祝投资顺利。
