stop the loop after first five values

when a condition is satisfied the loop puts a string value called "buy" in the column but i want to stop that loop upto five "buy" only in the column and then move to the second loop after this is fulfilled.

THE CODE IS AS FOLLOWING:

buycash=0;

sellfut=0;

buylongspread=0;

buy=0;

for ii=1:r

if(ds3.LongAvailableSpread(ii)>=ds3.MeanLongAvailableSpread(ii)&&ds3.LongAvailableSpread(ii)>=40&&ds3.CashBestAskVol(ii)>=3000&&buy==0)

ds3.CashStatus(ii)="buy"; * I WANT UPTO FIVE BUY'S IN THE CASH STATUS

COLUMN WHEN THE ABOVE IF CONDITION IS FULFILLED

AND WHEN IT IS FULFILLED

I WANT TO MOVE TO THE BELOW IF CONDITION*

ds3.FutStatus(ii)="sell";

buylongspread=ds3.LongAvailableSpread(ii);

ds3.CASHPosition_Price(ii)=ds2.CashBestAsk(ii);

buycash=ds2.CashBestAsk(ii);

ds3.FUTPosition_Price(ii)=ds1.FUTBestBid(ii);

sellfut=ds1.FUTBestBid(ii);

buy=1;

end

if ((ds3.ShortAvailableSpread(ii)>=0 || ds3.ShortAvailableSpread(ii)>=40-buylongspread)&&(ds3.CashBestBidVol(ii)>=3000)&&(buy==1))

ds3.CashStatus(ii)="sell";

ds3.FutStatus(ii)="buy";

ds3.CASHPosition_Price(ii)=ds2.CashBestBid(ii);

ds3.FUTPosition_Price(ii)=ds1.FUTBestAsk(ii);

ds3.cashpnl(ii)=ds2.CashBestBid(ii)-buycash;

ds3.futpnl(ii)=sellfut-ds1.FUTBestAsk(ii);

buy=0;

end

end
