One trade per day (only)

[stefy]

Hi

I developed a trading system which generates few signals per day (sometimes), but I want to take just the first signal of the day. One trade per day, and ignore the new triggers for the rest of the day.
How can I code that?

Thank you

Unfortunately this is beyond the scope what we can provide support for.

However, here are some hints:
- you could code a bool flag variable in your strategy which you set once the first signal triggered
- however, this approach will not work if you restart your strategy/NT, since the flag setting is lost and orders might have been placed. You then would need to persist the flag somehow e.g. in a file

Thank you, Dierk.

1) If I want to flag the trade, how can I do it? Any reference please? I don't know how to start, really.

2) My system generates two levels by 8AM and then I play breakouts (that's why I don't want to play it more than once a day).
There is no trade counter function or something else to simplify the problem?

Thank you again

Unfortunately I don't have any references at hand to assist you further.

Since I generate my own breakout levels, if I use such levels to create an order, and I generate the levels once a day, I will generate just one order per day. Correct?

[NinjaTrader_Dierk]

Sorry, not sure I follow.

I use the data between 0AM and 8AM to generate two levels.
Then my system looks for a breakout (support/resistance) to enter the trade.
Since I generate such levels once a day, can I make my order conditional to such level to be different from yesterday's level?
In this way, I will make sure to trade once a day.
Am I correct?

This is a logic question and unfortunatley I don't follow. From a logic standpoint, if you want to have only one trade per day, you need to trigger this off of something that indicates you have taken a trade.

Here is a brief example. You could create a strategy level variable named:

private bool takenTrade = false;

then in OnBarUpdate()

if (FirstBarOfSession) takenTrade = false;

if (tradeCondition == true)
{
takenTrade = true;
EnterLong();
}

Ray,

I did as you suggested, but after the first trade, it won't trade anymore (since the boolean condition is met).
In the back test, I get just one trade for each security.

My suggestion is guidance...You will have to debug to see what is happening.

Ray,

I understood I need to "refresh" the boolean back to false at the beginning of each day.
Something like: if time is 00.00.00 (new day kicks in), boolean takenTrade = false.

I went through the online manual but could find any hint.

Thank you

See post #8 for the example I provided.

FirstBarOfSession

I think I made the code right, but it doesn't work every day (sounds weird, I know).

I wrote in Initialize():
private DateTime RefreshDateTime;

In OnBarUpdate():
if (Time[0].Date > RefreshDateTime)

{
RefreshDateTime = new DateTime(Time[0].Year, Time[0].Month, Time[0].Day, 0, 0, 0);

takenTrade = false;
}

Like this it should refresh at the very beginning of each day.

Sometimes though there are no trades - maybe I should put the whole code in Initialize() ?

Thank you

You will have to debug it.
