写了一个网格交易的模型，单行执行没有问题，但是改成循环语句就出问题了，感觉好像不是完全执行完第一个循环再去执行第二个循环，而是整体在执行循环，请问是哪里出了问题？

单行是可以执行的：

input: P(2600,0,50000,1), J(3,1,10,1),N(10,1,100,1); //初始价格，网格宽度，每笔手数

if TREMAINQTY(1,'','')<=0*n then
tbuy(c>=p-9*j&&tholding2<=9*n,n,lmt,p-9*j);

if TREMAINQTY(1,'','')<=1*n then
tbuy(c>=p-8*j&&tholding2<=8*n,n,lmt,p-8*j);

if TREMAINQTY(1,'','')<=2*n then
tbuy(c>=p-7*j&&tholding2<=7*n,n,lmt,p-7*j);

if TREMAINQTY(1,'','')<=3*n then
tbuy(c>=p-6*j&&tholding2<=6*n,n,lmt,p-6*j);

if TREMAINQTY(1,'','')<=4*n then
tbuy(c>=p-5*j&&tholding2<=5*n,n,lmt,p-5*j);

if TREMAINQTY(1,'','')<=5*n then
tbuy(c>=p-4*j&&tholding2<=4*n,n,lmt,p-4*j);

if TREMAINQTY(1,'','')<=6*n then
tbuy(c>=p-3*j&&tholding2<=3*n,n,lmt,p-3*j);

if TREMAINQTY(1,'','')<=7*n then
tbuy(c>=p-2*j&&tholding2<=2*n,n,lmt,p-2*j);

if TREMAINQTY(1,'','')<=8*n then
tbuy(c>=p-j&&tholding2<=n,n,lmt,p-j);

if TREMAINQTY(1,'','')<=9*n then
tbuy(c>=p&&tholding2<=0,n,lmt,p);

if TREMAINQTY(4,'','')<=9*n then
tsell(c<=p-8*j&&tholding2>=10*n,n,lmt,p-8*j);

if TREMAINQTY(4,'','')<=8*n then
tsell(c<=p-7*j&&tholding2>=9*n,n,lmt,p-7*j);

if TREMAINQTY(4,'','')<=7*n then
tsell(c<=p-6*j&&tholding2>=8*n,n,lmt,p-6*j);

if TREMAINQTY(4,'','')<=6*n then
tsell(c<=p-5*j&&tholding2>=7*n,n,lmt,p-5*j);

if TREMAINQTY(4,'','')<=5*n then
tsell(c<=p-4*j&&tholding2>=6*n,n,lmt,p-4*j);

if TREMAINQTY(4,'','')<=4*n then
tsell(c<=p-3*j&&tholding2>=5*n,n,lmt,p-3*j);

if TREMAINQTY(4,'','')<=3*n then
tsell(c<=p-2*j&&tholding2>=4*n,n,lmt,p-2*j);

if TREMAINQTY(4,'','')<=2*n then
tsell(c<=p-j&&tholding2>=3*n,n,lmt,p-j);

if TREMAINQTY(4,'','')<=1*n then
tsell(c<=p&&tholding2>=2*n,n,lmt,p);

if TREMAINQTY(4,'','')<=0*n then
tsell(c<=p+j&&tholding2>=n,n,lmt,p+j);

循环执行会出现问题:

input: P(2600,0,50000,1), J(3,1,10,1),N(10,1,100,1),M(10,1,30,1); //初始价格，网格宽度，每笔手数，网格数量

FOR i=1 TO M DO

if TREMAINQTY(1,'','')<=(i-1)*n then
tbuy(c>=p-(10-i)*j&&tholding2<=(10-i)*n,n,lmt,p-(10-i)*j);

FOR u=1 TO M DO

if TREMAINQTY(4,'','')<=(10-u)*n then
tsell(c<=p-(9-u)*j&&tholding2>=(11-u)*n,n,lmt,p-(9-u)*j);
