Comparing today's open to yesterday's close on EOD data

[el_spudo]

I'm trying to get more familiar with NinjaScript and I was trying to write a simple strategy that looked at yesterday's close and today's open.

I've imported end of day data into NinjaTrader, and with the code below, am not getting the results I expected.

        protected override void Initialize()
        {
            CalculateOnBarClose = true;
            ExitOnClose = true;
        }

        /// <summary>
        /// Called on each bar update event (incoming tick)
        /// </summary>
        protected override void OnBarUpdate()
        {
            // Condition set 1
            // Is Close[-1] yesterday's open? Is Open[0] today's open?
            if (Open[0] < Close[-1])
            {
                EnterLong(DefaultQuantity, "MyBuy");
            }
        }

When I look at the chart in the Backtest summary, it seems that I buy at today's open and sell at tomorrow's open. How can I ensure to buy at today's open and sell at today's close?

el_spudo,

You are using the [] indexes wrong. 0 refers to the most recent bar, 1 refers to the previous bar. To get yesterday's values you want to do [1] provided you are using daily charts.
