# Correlation EA assistance needed

605

Im still learning alot regarding mt4 programming

Basically saw the idea regarding correlation and bolligner bands

Buy on the EUR/USD if price is below the middle line (20SMA) of the bands on the EUR/USD pair and price as crossed and closed below the lower band on the USDCHF pair

Sell on the EUR/USD if price is above the middle line (20SMA) of the bands on the EUR/USD pair and price as crossed and closed above the higher band on the USDCHF pair

Questions:

Just need to know if my logic is correct regarding my code below  ?

If I state "USDCHF" and "EURUSD" inside the ibands will it check the logic on the "USDCHF"pair and place a trade on "EURUSD" if I place the EA on the EURUSD chair ?

Or this there a different approach of looking at it ?

Code:

```   if(Cross(0, Close[1] < iBands("USDCHF", PERIOD_CURRENT, 20, 2, 0, PRICE_CLOSE, MODE_LOWER, 0)) //Candlestick Close crosses above Bollinger Bands
&& Close[1] < iMA("EURUSD", PERIOD_CURRENT, 20, 0, MODE_SMA, PRICE_CLOSE, 0) && Close[1] <  iBands("EURUSD", PERIOD_CURRENT, 20, 2, 0, PRICE_CLOSE, MODE_LOWER, 0)
)
{
RefreshRates();
SL = 30 * myPoint;
TP = 30 * myPoint;
{
if(ticket <= 0) return;
}
else
myOrderModifyRel(ticket, 0, TP);
myOrderModifyRel(ticket, SL, 0);
}
```

SELL

```if(Cross(1, Close[1] > iBands("USDCHF", PERIOD_CURRENT, 20, 2, 0, PRICE_CLOSE, MODE_HIGH, 0)) //Candlestick Close crosses below Bollinger Bands
&& Close[1] > iMA("EURUSD", PERIOD_CURRENT, 20, 0, MODE_SMA, PRICE_CLOSE, 0) && Close[1] < iBands("EURUSD", PERIOD_CURRENT, 20, 2, 0, PRICE_CLOSE, MODE_HIGH, 0)
)
{
RefreshRates();
price = Bid;
SL = 30 * myPoint;
TP = 30 * myPoint;
{
ticket = myOrderSend(OP_SELL, price, TradeSize, "");
if(ticket <= 0) return;
}
else
myOrderModifyRel(ticket, 0, TP);
myOrderModifyRel(ticket, SL, 0);
}
}```

1°)specify which Close[1] :  close of EU or UC ?

2°)maybe it's better to place trade order on the openning of new canlde (candle 0) if previous one (candle 1) fulfill all conditions

```bool buy_condition=(iClose("USDCHF",PERIOD_CURRENT,1) < iBands("USDCHF", PERIOD_CURRENT, 20, 2, 0, PRICE_CLOSE, MODE_LOWER, 1)
&& iClose("EURUSD",PERIOD_CURRENT,1) < iMA("EURUSD", PERIOD_CURRENT, 20, 0, MODE_SMA, PRICE_CLOSE, 1));

```

//sell conditions

```bool sell_condition=(iClose("USDCHF",PERIOD_CURRENT,1) > iBands("USDCHF",PERIOD_CURRENT,20,2,0,PRICE_CLOSE,MODE_UPPER,1)
&& iClose("EURUSD",PERIOD_CURRENT,1) > iMA("EURUSD", PERIOD_CURRENT, 20, 0, MODE_SMA, PRICE_CLOSE, 1));```

1. Well Ill check if the candle close above/below the bands on the UC then confirm on the EU if the price is above the middle band and take the trade on the EU
