Dear Users, Traders, and Programmers.
Here is a following Code for EA in MT4 written in MQL4 : And after you will find the same code for Zorro Trader, compared.
__________________________________________________________________________
// MT4 version
// enter a trade when the RSI12 crosses over 75 or under 25
int start()
{
// get the previous and current RSI values
double current_rsi = iRSI(Symbol(), Period(), 12,
PRICE_CLOSE, 1); // mind the '1' - candle '0' is incomplete!!
double previous_rsi = iRSI(Symbol(), Period(), 12, PRICE_CLOSE, 2);
// set up stop / profit levels
double stop = 200*Point;
double takeprofit = 200*Point;
// correction for prices with 3, 5, or 6 digits
int digits = MarketInfo(Symbol(), MODE_DIGITS);
if (digits == 5 || digits == 3) {
stop *= 10;
takeprofit *= 10;
} else
if (digits == 6) {
stop *= 100;
takeprofit *= 100;
}
// find the number of trades
int num_long_trades = 0;
int num_short_trades = 0;
int magic_number = 12345;
// exit all trades in opposite direction
for(int i = 0; i < OrdersTotal(); i++)
{
// use OrderSelect to get the info for each trade
if(!OrderSelect(i, SELECT_BY_POS, MODE_TRADES))
continue;
// Trades not belonging to our EA are also found, so it's necessary to
// compare the EA magic_number with the order's magic number
if(magic_number != OrderMagicNumber())
continue;
if(OrderType() == OP_BUY) {
// if rsi crosses below sell level, exit long trades
if((current_rsi < 25.0) && (previous_rsi >= 25.0))
OrderClose(OrderTicket(), OrderLots(),
Bid, 3, Green);
else
// otherwise count the trades
num_long_trades++;
}
if(OrderType() == OP_SELL) {
// if rsi crosses over buy level, exit short trades
if((current_rsi > 75.0) && (previous_rsi <= 75.0))
OrderClose(OrderTicket(), OrderLots(),
Ask, 3, Green);
else
// otherwise count the trades
num_short_trades++;
}
}
// if rsi crosses over buy level, enter long
if((current_rsi > 75.0) && (previous_rsi <= 75.0)
&& (num_long_trades == 0)) {
OrderSend(Symbol(), OP_BUY,
1.0, Ask, 3,
Ask-stop, Bid+takeprofit,
"", magic_number,
0, Green);
}
// if rsi crosses below sell level, enter short
if((current_rsi < 25.0) && (previous_rsi >= 25.0)
&& (num_short_trades == 0)) {
OrderSend(Symbol(), OP_SELL,
1.0, Bid, 3,
Bid+stop, Ask-takeprofit,
"", magic_number,
0, Green);
}
return(0);
}
________________________________________________________________
Now Compare it to the following code which does the same in Zorro Trader :
________________________________________________________________
// Zorro version
// enter a trade when the RSI12 crosses over 75 or under 25
function run()
{
// get the RSI series
vars Close = series(priceClose());
vars rsi12 = series(RSI(Close,12));
// set up stop / profit levels
Stop = 200*PIP;
TakeProfit = 200*PIP;
// if rsi crosses over buy level, exit short and enter long
if(crossOver(rsi12,75))
reverseLong(1);
// if rsi crosses below sell level, exit long and enter short
if(crossUnder(rsi12,25))
reverseShort(1);
}
