>= working but not > only

[algofy]

My strategy is in NT 8.

In OnBarUpdate() I have the following vars:

int lowestBarsAgo = LowestBar(Low, Bars.BarsSinceNewTradingDay)
double lowestPrice = Low[lowestBarsAgo]

then in my trade logic


if (Close[0] >= Open[0] && Low[0] <= lowestPrice)
<enter trade logc>

so here's the issue, when I have the above Low[0] <= lowestPrice it works as expected but when I change it to Low[0] < lowestPrice it doesn't run as expected. Any thoughts or suggestions as to why less than or equal works but not less than only?

Hello algofy,

This appears to be a logic related question, however, I think what may be going on is that you are finding the lowest low since the open. Then you are trying to see if the current low is lower than the lowest low. If the current bar's low is the lowest low already, it won't be lower than itself. But it could be equal to itself.

ahh that makes sense, looking at my code do you know of an easy way to exclude the [0] bar in that lowest bar look back?

Hello algofy,

If you just want to know if the current low is lower than the lowest low not including the current bar, you can use the MIN() method.

For example:

if (Low[0] < MIN(Low, Bars.BarsSinceNewTradingDay)[1])

MIN(ISeries<double> input, int period)[int barsAgo]
