Previous price on "On Price Change" strategy

[Ousher]

A buy order will be executed when the following is met

The current price (Close[0]) is 1 tick higher than the previous closed bar's high (High[1])
+
the previous price (Close[??]) was equal to the previous bar's high (High[1]).

How do I point to the previous price change since Close[1] would point to the previous bar, not the previous price change?

Thanks!

Hello Ousher, thanks for writing in.

You can keep track of the last changed price by saving the last price at the end of OnBarUpdate e.g:

private double lastPrice = -1;
protected override void OnBarUpdate()
{
Print("lastPrice " + lastPrice);
Print("Close[0] " + Close[0]);
Print("");

if(Close[0] != lastPrice)
lastPrice = Close[0];
}

Best regards,
