how to make a trade with a cycle?

[natsirte]

hi

I have an EA and I'd like to make it works with a cycle.

I've got 5 variables

double ma1 = iMA(NULL, 0, 1, 0, MODE_EMA, PRICE_CLOSE, Current + 0);
double sar = iSAR(NULL, 0, 0.02, 0.2, Current + 0);
double Macd=iMACD(NULL,0,12,26,9,PRICE_CLOSE,MODE_MAIN,Current + 0);
double Signal=iMACD(NULL,0,12,26,9,PRICE_CLOSE,MODE_SIGNAL,Current + 0);
string var_trading="ok";

the conditon for a trade is :

******************************

if (Period()==1)
{
double ma_buy = ma1>sar && Macd>Signal && var_trading=="ok" ;

}

******************************

And this is what i want :

1/the trade beginning
2/the value for var_trading became "no" --> var_trading="no"
3/ End of the trade (Takeprofit or stoploss)
4/The new trade can begin because var_trading=="no"
5/ IMPORTANT : when ma1 < sar ==> var_trading=="ok"
6/ When ma1 > sar again and if Macd>Signal ====> a new trade beginning!
7/ and the value for var_trading became "no" --> var_trading="no"
8/ etc....

*******************************

How can I do?

For many reasons, I don' want this (see my code please)

double ma_buy = ma1p1<sarp1 && ma1>sar && Macd>Signal && var_trading=="ok" ;

Best regards
