Only looking at the most current three candles

[Seastragg]

Hi,

I want to build logic into a strategy to only look at the current and the next 2 previous candles (ie. candles 2, 1, and 0). I don't care about any of the previous candles, and I don't need it to be backtested. I only want the strategy to look at those three candles.

Does anyone know if that's possible?

Cheers,
Jack

Hi Jack, thanks for writing in.

Price data can be looked back upon with indexing e.g.

if(CurrentBar < 2) return;

Print(Close[2]);//third from last bar
Print(Close[1]);//second from last bar
Print(Close[0]);//latest bar

to ignore the historical data, add if(State == State.Historical) return; to the top of OnBarUpdate. Here is a list of all available price series:

I don't know if that's what I'm looking for. Essentially, I have a button that I can push to start looking for a setup, and when I push it, I want it to only look at the most current candles and then take a trade off of some specific inputs. Currently, it keeps looking back constantly, and takes trades I don't want it to because certain conditions are being met by candles that are already meet those conditions.

I guess what I'd like is for me to start my strategy, and it waits for 0 to close and then starts looking for my setup. Ie. The flow that would be most ideal is, strategy initiated, it waits for the current candle 0 to close (turning into [1]), then the strategy looks for the setup to occur on the current candle [0].

Is there a way to make it wait for the most recent candle to finish?

Hi Seastragg,
In addition to adding if(State == State.Historical) return; to the top of OnBarUpdate as suggested by ChrisL, perhaps an idea to look at percentcomplete on start up when trading realtime and log the number of the first closing bar to a variable?

Hi Jack, thanks for your reply.

If you ignore the historical data with if(State == State.Historical) return; the next bar to close will be the latest bar on the chart. If you do not ignore the historical data all bars on the chart will be processed in OnBarUpdate.

Kind regards,

I guess I'm unsure where it goes. I tried this configuration and it didn't work. Does it go somewhere else?

protected override void OnBarUpdate()
{
if(State == State.Historical) return;
if (longButtonClicked
&& setup inputs etc

Hi Jack, thanks for your reply.

A button click event should not be captured within OnBarUpdate. I linked an example you can follow if you would like to submit orders by a button in an indicator:

Hi Chris,

That is exactly the button file I am using. It has the button click in the OnBarUpdate() as seen from this copy pasta. I have my own setup that I have put into the long and short(and it's taking trades as I intended, except sometimes it takes trades as soon as the button is clicked). What I would like is for the strategy to not start looking for my setup inputs until the bar that I click the long/short button to close. Ie. if I click the button within a 5 minute candle at 10:12, I want the setups to start being looked at once that candle closes at ~10:15;01.

Can you please help me understand where the "if(State == State.Historical) return;" should go in that button file?

protected override void OnBarUpdate()
{
if (longButtonClicked
&& Close[1] >= MAX(High, 2)[2] + 0 * TickSize
&& High[1] < CurrentDayOHL().CurrentHigh[1]
&& High[0] > High[1])
EnterLong();

if (shortButtonClicked
&& Low[1] > CurrentDayOHL().CurrentLow[1]
&& Low[0] < Low[1]
&& Close[1] < MIN(Low, 2)[2] - 0 * TickSize)
EnterShort();

if (!longButtonClicked
&& Position.MarketPosition == MarketPosition.Long)
ExitLong();

if (!shortButtonClicked
&& Position.MarketPosition == MarketPosition.Short)
ExitShort();
}

Hi Jack, thanks for your reply and sorry for the oversight.

Instead of calling EnterLong, you would need to keep track of the CurrentBar property and set a flag similar to this:

private int cb;
private bool flag = false;
protected override void OnBarUpdate()
{
if(State == State.Historical) return;



if (longButtonClicked

&& (Position.MarketPosition == MarketPosition.Flat)
//&& (IsRising(EMA1) == true)
//&& (IsRising(EMA2) == true)
)// && (IsRising(EMA3) == true))

{
cb = CurrentBar;
flag = true;
}

if(CurrentBar == cb+1 && flag)
{
EnterLongLimit(GetCurrentBid(0),"Long");
}

To have a button that immediately responds to the click, you would need to use an Addon style Account object and submit orders with the Submit() method when the WPF button is clicked.
