Where to start if I want to create a strategy on a trading set-up?

[belecona]

Hi Ryan

Thanks for your best wishes. I'm embarrassed to report that it has not triggered a long trade (supposed to with the condition met)!

Must I have a chart with all the indicators of the strategy or a plain one will do when running a strategy? I have the strategy on a 4-tick MedianRenko chart and not with the indicators.

Note: It worked in the morning with the never-ending trades triggered!

Please help again .. sorry .. sigh ..

You don't need the indicators applied to a chart. You can add

TraceOrders = true;

to your initiliaze section to help debug. Click tools > output window to see this.

Also take a look at the link below which covers some general debugging tips you should use:

One thing may be that you are already in a strategy position from historical data.

If you only want your strategy to run in real-time you can add the statement below:

 
if (Historical)
   return;

Not sure if that's what's going on though. Best is debug with TraceOrders and follow some of the guidelines in that post.

Thanks Ryan. I will add the following codes to my script:

TraceOrders = true;

if (Historical)
return;

Oh, the output window is blank.

I'm currently reviewing my scripts and may start creating a new batch. You will hear from me "for sure" .. smile ..

Break time for me as I have a big head!! Continue enjoying your afternoon.

Hi Ryan

1 more question please for this afternoon. How can I tell the system NOT to place a trade (even the long or short condition is met) IF say

Indicator 1 = 0

Appreciate your directing me to find it out. The No Trade condition will prevent choppy trades.

Thank you!

Hi Belecona,

You add a condition to your entry to check that the indicator is not 0.

 
if (allYourOtherConditions && Indicator[0] != 0)
   doSomething;

Hi Ryan

Your super-swift response has made me feel like a VIP. Thank you.

Let me clarify the following:

1. != stands for not

I will have 1 more gadget upon your kind confirmation. Thanks for making my life easier!

[NinjaTrader_RyanM1]

Yes, that's correct. != not equal to

[belecona]

sos again ..

Good morning Ryan

1. I want the VertLine crossing the Zero line for Exit. Do I have it right?

// Exit with warning signals of trend reversal


if (CrossBelow(d9ParticleOscillatorWVertLineR(7, 0).RawTrend, 0, 1)

ExitLong();

2. I tried !> (thought it may mean not greater than) and got an error message.

I must have done something wrong .. sigh .. Please help me! Thank you.

[NinjaTrader_RyanM1]

Hi Belecona,

1) Will exitlong once ...vertlineR.RawTrend crosses below 0

2. This is not correct usage of not greater than. Operator for this is < or "less than"

All C# operators below:

Thanks Ryan.

My petite head was too "stuffed" last night when I tried !>. Sorry! After playing with strategies for just a week, I now understand why most of my programming peers have "silver" hair at a young age.

Another question please - Are the following the same? If yes, which one is more effective in your opinion?

1. Rising(Indicator1)
2. Indicator1[0]>Indicator1[1]

Big Big Thank You!

[NinjaTrader_RyanM1]

Yes, these should be the same. Rising is just an easier way of expressing this.

[belecona]

Thanks Ryan! Bingo for me .. haha ..

You maybe glad to learn that I've enough materials to play with this afternoon + weekend. Will pick your brains again next week.

Thank You .. Thank You again from the bottom of my petite heart for your prompt guidance and support! Have a Relaxing weekend.

[NinjaTrader_RyanM1]

Thanks for the well-wishes! May you have a productive weekend with NinjaScript.

Hi Ryan

I stand a better chance of having a productive weekend if you don't mind answering one more question for me please, ie

I've been trying to adapt a sample strategy with trail stop and cancel orders etc (all the goodies that I would like to have) to mine. I only replaced its entry and exit conditions. F5 has been giving me Successful Compile messages. Yet when I backtested the strategy (almost 10 times with changes here and there - tried to make it work), it has been generating 0 trade forever.

I'm thinking maybe the strategy will work on live data and just not backtesting. What do you think?

Appreciate your guidance again (as always). Thank you.

[NinjaTrader_RyanM1]

Hello Belecona,

One of my suggestions earlier was to run your code on only live data. This was accomplished with the statement:

 
if (Historical)
  return;

If you don't have this statement and it's not trading in a backtest, can you reply with the code you're using.
