Difference between Open Close

[edgeliner]

How do you state in a strategy that if the open is 30 pips greater than the close, sell........??

Hello,

You first would need to declare a variable to store the calculation of the difference between the open and the close.

double difference = Open[0] - Close[0];

Next, you would then need to create a condition to check when this was more than 30 pips

if (difference > 30)
            {
            // enter your short position
            }

Thanks Matthew!

Matthew....I am getting an error message from this.....any idea why?????

#region Variables
// Wizard generated variables
private int myInput0 = 1; // Default setting for MyInput0
// User defined variables (add any user defined variables below)
double difference = Open[0]-Close[0];

{
SetProfitTarget("", CalculationMode.Ticks, 10);

Hi edgeliner,

You can't access those bar objects there in variables region. Best practice here is declaring in Variables region, and then assign in OnBarUpdate() as example below.

#region Variables
// Wizard generated variables
private int myInput0 = 1; // Default setting for MyInput0
// User defined variables (add any user defined variables below)
private double difference;
#endregion

protected override void OnBarUpdate()
{
difference = Open[0]-Close[0];
//rest of code here. 

}

Oh, that's right! I should have known that!! Thanks a bunch Ryan!!!!

[edgeliner]

OK.....all set with regard to compiling.....but for some reason, it never opens a position?????

protected override void OnBarUpdate()
{

{
//Only run on real-time data. This will prevent your strategy from executing on historical data and basically will now run on real-time data only!
if (Historical)
return;
}
difference = Open[0]-Close[0];

// Condition set 1
if (Position.MarketPosition == MarketPosition.Flat
&& (difference >= 10)
&& (Close[0] > Open[0]))
{
EnterLong(10000, "");
}

// Condition set 2
if (Position.MarketPosition == MarketPosition.Flat
&& (difference <= -10)
&& (Close[0] < Open[0]))
{
EnterShort(10000, "");
}

No entries usually means your condition is never true.

If you're talking about pips and a difference of 10, this may explain it. You would never see a difference of 10 from Open[0] - Close[0] when looking at EURUSD, for example.

To check difference of 10 pips, make this change:
difference >= 10 * TickSize

It's always good to print all values and verify through Tools > Output Window. This post can help with this:

You are awesome Ryan! Why didn't I think of that????

[edgeliner]

This is crazy Ryan! You were right about the EURUSD.....and I change it, but it still did not open any positions????

difference = Open[0]-Close[0];

// Condition set 1
if (Position.MarketPosition == MarketPosition.Flat
&& (difference >= 10 * TickSize)
&& (Close[0] > Open[0]))
{
EnterLong(10000, "");
}

// Condition set 2
if (Position.MarketPosition == MarketPosition.Flat
&& (difference <= -10 * TickSize)
&& (Close[0] < Open[0]))
{
EnterShort(10000, "");
}

It's the same item - the condition never evaluates true. You will need to learn to check values through print statements so you can verify this on your end.

Print(difference); and check using Tools > Output Window.

These two conditions will never be true together.
difference >= 10 * TickSize
Close[0] > Open[0]

Break this down with some hypothetical values and you can see why it might never be true.

Open = 100
Close = 112

110 - 112 = -12

Basically -- for every bar where Close > Open, the difference between Open - Close on these bars will always be a negative value.
