Run the Strategy Only Once in Tradestation

[einja 10]

hi everyone,

 

i am new to this Tradestation and EasyLanguage scripting.

 

i am looking for a simple script that places an order once and maybe close it at a certain price. closing is not crucial.

 

Ex. if EURUSD is trading at 1.3356, and the trend is downwards, i want to pass the parameter 1.334 and the order for sell short should be executed. once its executed, the script should become non operational otherwise, it will keep shorting since the condition, if Price <= 1.334 will be triggered many times.

 

thanks for the people who are reading this and trying to help people like me who are beginners.

If current shares = 0 then begin

If Price <= 1.334 then buy/sell x contracts at market;

end;

Try something like:

 

If marketposition=0 then
sellshort next bar at 1.334;

 

When you have an existing short position then marketposition=-1 and when you have an open long position then marketposition=1. This is regardless of the number of shares/contracts you hold. When you are flat market position=0.

 

Note that both this method and UrmaBlume's will permit a new position to be initiated if the prior position has been exited and then price trades back down to 1.334.

 

You may want to limit yourself to one entry per day at this level, in which case your code might look like this:

 

If entriestoday=0 then
sellshort next bar at 1.334;

 

There is no need to state a condition for marketposition because if there have been no entries you must already be flat (unless you're holding positions overnight). If you allow a specified number of positions each day - say four - then you'd need:

 

If marketposition=0 and entriestoday=4 then
sellshort next bar at 1.334;

 

I see no reason for the "begin . . . end" loop in Urma's code, a specific price would normally be specified, and "this bar" can be used instead of "at market", so this could be edited to something like:

 

If current shares=0 and close<=1.334 then 
buy this bar;

 

Most likely the difference may be because Urma is using the MultiCharts version of EasyLanguage.

 

Hope that helps.

 

Kind regards,

UrmaBlume and BlueHorse,

 

Your guys are amazing. Thank you and i read your replies before too on other posts. Keep up the good work.

 

This is what i was looking for. I see a trend on the chart and it could be a 3rd run or 15th run in that day. once i jump in, it needs to execute once and then get out.

 

This is the psuedo code.

 

1. see the chart pattern (eyeballing and manual).

2. Execute the strategy:

{

Short Sell at specific price.

After some time buy back the same stock

} >> This brasis code should be run once and the strategy should be exited or dys-functional.

I think you already have your answer above, don't you?

 

Not sure why you even need an automated strategy for this though - why not just place a resting order at the price level you want, as it sounds like you're going to be around to watch the whole process unfold?

i have a long position.

 

i get "not Executed 0.00" printed in the output window.

 

marketposition does not return 1 when i have a long position.

 

 

if MarketPosition = 1 then

BEGIN

Sell All Contracts Next Bar At Market;

 

Print( "yes Executed" );

END

Else

BEGIN

Print( "not Executed", marketposition );

END

i am using a simulated account of tradestation.

 

do u know if i can place orders in sim. acct using the code u sent. nothing happens when i run the strategy. i am wondering if the script can be used for just back testing or can we use it for placing orders real time also.

[BlueHorseshoe 10]

You can use place orders in SIM, but only for instruments of the same type as the account. In other words, if you have a TS Forex account, you can't live SIM trade a futures contract. This is because the data-feed is not live, and you're getting delayed data. There is no way around this (TS will not allow you a live Futures feed to a Forex or Securities account, as far as I am aware).

 

Does this sound applicable?
