implementing my first strategy

[platax]

Hello,

I'm discovering the great NT strategy wizard : it seems so simple that I hardly understand why I need help, but I still do

I'd like to fix a high and a low price reference beetween 9.30 and 10.00 to trade only if a certain level is reached above the high or below the low price.

My concern is, how can I automate the reference prices through the wizard ?

I can see there are time and price data but can't figure out how to connect them, and how to draw the time interval.

I guess it takes a specific way of thinking that I still haven't imagined.

Hello platax,

Thank you for your post and welcome to the NinjaTrader Support Forum!

This would require unlocking the code to develop your method to find the high and low between these two times. So this would unfortunately not be possible in the Strategy Wizard.

We have Premium Paid Educational events designed to provide you with an in depth look at programming indicators and automated strategies through the use of NinjaScript:

Thanks Patrick. I might try to code the following then : what follows is a kind of "let alone syntax" draft.

// user variables

FirstMinuteReference // first minute of the reference period
LastMinuteReference // last minute of the reference period

FirstMinuteToEnter // first minute to enter trade.
LastMinuteToEnter // last minute to enter trade.

LastMinuteToExit //last minute to exit trade.

MinBreakoutRatio // minimum breakout ratio

StopLosspRatio // loss ratio tolerated before exit
StopGainRation // gain ratio expected to exit



// calculated variables

Time // time in minutes from opening hour

MinPriceRef // minimum price recorded during reference interval
MaxPriceRef // maximum price recorded during reference interval

LowerExitPrice // lower exit price
UpperExitPrice // upper exit price


if Time >= FirstMinuteReference and  <= LastMinuteReference // we are inside reference interval : let's set the reference prices
	set MinPriceRef
	set MaxPriceRef

if Time >= FirstMinuteToEnter and  <= LastMinuteToEnter // we are inside the trade interval : let's see if there is a trade
	if price >= MaxPriceRef + (MaxPriceRef x MinBreakoutRatio) // bullish trend
		trade long
		set LowerExitPrice = Price - (Price x StopLosspRatio)
		set UpperExitPrice = Price + (Price x StopGainRatio)

	if price <= MinPriceRef - (MinPriceRef  x MinBreakoutRatio) // bearish trend
		trade short
		set LowerExitPrice = Price - (Price x StopGainRatio)
		set UpperExitPrice = Price + (Price x StopLosspRatio)
		
	if price <= LowerExitPrice or price >= UpperExitPrice or BarNumber >= MaxBarToExit // let's get out of this trade
		close position

I'm surprised not to find an equivalent to download : most breakout strategies I found seemed to hard codes the variables instead of letting them user defined. I'd like one that could take advantage of NT optimization function

I can't admit that I'm the first to try this : has anyone posted a similar breakout strategy with optimization variables somewhere ?

Hello platax,

Thank you for your response.

You can check our file sharing section to see if one of our users has such a strategy available for download: http://www.ninjatrader.com/support/f...splay.php?f=37

How can I make any test upon time ?

Unfortunatly I have not found what I'm looking for. BTW this will introduce me to hard coding in C#.

I would still appreciate a good help with the wizard but this is my concern : in the condition builder, "Time value" is set in a time format (00:00 tot 23:59) and my declared variables can only be bool, double, int or string.

How can I make any test upon time ?

Hello platax,

Thank you for your response.

Ints are used to compare the time series, so you can use ints like 80000 for 8 AM and 161500 for 4:15 PM.

The wizard is more touchy : I get the message

Return type of left expression 'DateTime' and right expression 'Int32' do not match.
You need to select a different item

Hello platax,

Thank you for your update.

What are you attempting to do by comparing static values? I believe you wish to compare the current time against a user variable, so you would select Time Series not Time Value.

[platax]

Hello Patrick,

Thanks for this hint,

You're right but... time series unit is "bars ago" which is not what I'm looking for. I would like to compare present time (9:35) or minutes elapsed since market opening (5) to user value (10)

If "bars ago" is the only dynamic time serie available, this makes me hard code a counter for each elapsed bar that can be substracted to present bar to now where I am in time frame. Not so neat indeed...

[NinjaTrader_PatrickH]

Hello platax,

Thank you for your response.

You would need to hard code this into the strategy, but there would be no need for the counter as you can store the Open time and check the current time is greater, then subtract the difference.

Please let me know if you have any questions.
