Low of last 7 days

[no111]

Hi there,

I want a very simple system, just buy when the close is the low of last 7 bars (and close is above 200SMA)
Does anybody know what's wrong with this code?

       protected override void Initialize()
        {
            Add(SMA(200));

            CalculateOnBarClose = true;
        }
  protected override void OnBarUpdate()
        {
            // Condition set 1
            if (Close[0] > SMA(200)[0]
                && Close[0] == LowestBar(DefaultInput, 7))
            {
                EnterLong(DefaultQuantity, "long");
            }

Please try using MIN instead of LowestBar -

Thanks that works.

But now I want to close that position when it is highest close of last 7 days.
But this doesn't work:

        protected override void OnBarUpdate()
        {
            // Open Long
            if (Close[0] > SMA(200)[0]
                && Close[0] == MIN(7)[0])
            {
                EnterLong(DefaultQuantity, "long");
            }

            // Exit Long
            if (Close[0] == MAX(7)[0])
            {
                ExitLong("ExitL", "Long");
            }
        } 

I know these are very basic questions, is there a kind of course I can follow?

NinjaScript as C# is case sensitive, please try this Exit condition below -

// Exit Long
if (Close[0] == MAX(7)[0])
{
ExitLong("ExitL", "long");
}
