# Check previous 10 candles/bars and determine the lowest close price

745

Hello forum, good day.

How could I make a function that checks the previous 10 candles/bars and determine the lowest close price of those candles/bars? After this I need to check if Close[0] < LowestClose and then assign StopLoss = AskPrice;

Best regards and thank you,

MQL4 ?

`double d_Lowest_Close = Low[iLowest(_Symbol, PERIOD_CURRENT, MODE_CLOSE, 10, 1)];`

I came up with this:

```double CalcStopLoss()
{
double sl;
double LowestClose  = Low[iLowest( NULL, 0, MODE_CLOSE, 10, 1 )];
double HighestClose = Low[iHighest( NULL, 0, MODE_CLOSE, 10, 1 )];

if ( Close[0] < LowestClose ) sl = Ask; //--- Buy Stop Loss
else if ( Close[0] > HighestClose ) sl = Bid; //--- Sell Stop Loss

return( sl );
}```

I add CalcStopLoss() at the Stop Loss argument in the OrderSend() function, but I get an OrderSend error 130, why is this?

double HighestClose = Low[iHighest( NULL, 0, MODE_CLOSE, 10, 1 )];

It is better to use syntax from modern versions of MQL4. Then do not have to re-write your codes soon + these designations is much easier to read and understand

double HighestClose = Low[iHighest( NULL, 0, MODE_CLOSE, 10, 1 )];

Typo? Must be High

if ( Close[0] < LowestClose ) sl = Ask; //--- Buy Stop Loss

else if ( Close[0] > HighestClose ) sl = Bid; //--- Sell Stop Loss

1. Do not forget that Buy-orders closes at Bid-prices, Sell-orders at Ask-prices
2. Maybe SL is too close to order open price?

I add CalcStopLoss() at the Stop Loss argument in the OrderSend() function

PS: double sl = 0;
