主题：最近N次交易的平均盈利点数怎么写

variable:num[]=0;
n:=0;
variable:m=0;
ma5:=ma(c,5);
acn:=3;                              //这个就是你定义的N次交易盈利

ma10:=ma(c,10);
kd:=cross(ma5,ma10);
pd:=cross(ma10,ma5);

if kd then begin
buy(holding=0,1,market);
end
if pd then begin
sell(holding>0,1,market);
if NUMPROFIT(1)>0 then
BEGIN
num:=NUMPROFIT(1);
m:=m+1;
end
end
temp:NUMPROFIT(1);

if m>acn-1 then
begin
for i=0 to acn-1 DO
begin
n:=n+num[ubound(num)-i];
end
end
aa:n/acn;
