Creating my own uptick/downtick counter

[kuroro13]

I'd like to create my own uptick/downtick counter due to some needs for other custom indicators I am developping .
Here is the idea :

"from the open to the close of each Bar ":
Up=0;
Dn=0; //reset upticks/downticks
Value1 = Close[0];
if (Value1>Close[1])
Up=Up+1;//count upticks
if (Value1<Close[1])
Dn=Dn+1;//count downticks

The thing is I don't know how to translate this idea "from the open to the close of each Bar ". My guess is that I should use the OnMarketData() method but I'm not sure.

Can anyone help ?

Try:

if (FirstTickOfBar)

It does not work. Here's what I get :

and the script :

protectedoverridevoid OnBarUpdate()
{
if (CurrentBar<1)
return;

if (FirstTickOfBar)
{
Up=0;
}
Value1 = Close[0];
if (Value1>Close[1])
Up=Up+1;

Plot0.Set(Up);
}

You need to be running with CalculateOnBarClose = false and this will only work in real-time.

Depending on how you are trying to justify what is an uptick and what is a downtick your logic will not work either. Close[1] refers to the previous bar's close. If you want to compare every tick against the previous bar's close then your logic will work. If you wanted to compare every tick against the previous tick to determine if it is up or down you will need different logic.

Code that has not been tested.

if (FirstTickOfBar)
{
     Up = 0;
     Down = 0;
}
prevTick = currTick;
currTick = Close[0];
if (currTick > prevTick)
     Up++;
else if (currTick < prevTick)
     Down++;

I want to compare the previous tick with the incoming tick.
What logic should I use ?

[NinjaTrader_JoshP]

The logic I posted in my previous post is for that case.

[kuroro13]

Sorry but it does not work.
The only value I get for each bar is 1 .
My CalculateOnBarClose is set to false. I don't understand...

[NinjaTrader_JoshP]

This will only work in realtime. There is no way for you to count ticks historically. You don't know what the ticks are doing intrabar on a historical bar.

Will NT7 handle upticks/downticks & Bid/Ask?

Not being able to create custom indicator using upticks/downticks or Bid/Ask is really annoying...
It's like playing guitar with a missing chord.

By the way, when will NT7 be launched ?

[NinjaTrader_JoshP]

Not sure I follow kuroro13. I just showed you how to do it NT6.5. You need to run it on real-time data.

Quick Question on this....

I have the code in and its runs without error. How to I get it to either plot on the chart or print the values on the chart?

Thanks

[NinjaTrader_JoshP]

If you want to plot on the chart you would need to create indicator plots and set those values to the plots. Please see the tutorials in the Help Guide for how to create plots.

If you want to print on the chart you can use either DrawText() or DrawTextFixed(). There are examples for these on the Help Guide too.

Without the ability to backtest a tick based strategy, you would have to forward test it for months or years and if you made a change to it, you would have to start forward testing over. There is also no way to optimize it.

NeoTicker has a function called "Tick Replay." As long as you have all of the tick data during the backtesting period for an instrument, you can replay the ticks and backtest the strategy. Would it be possible for Ninja to have a Tick Replay function in the future, so tick based strategies can be backtested?

[NinjaTrader_JoshP]

Hi shane,

NinjaTrader has a Market Replay feature. If you have recorded an instrument beforehand you can replay that instrument exactly how it happened live.

Hi Josh,

Doesn't IQfeed provide the upTicks and downTicks of a bar directly? Is there anyway to access it,without recalculating them using ninjascript?

Does zenfire also provide this information directly? In upcoming Ninja7 release,will this be accessible directly with IQfeed or zenfire?

Thanks
