How do I open a position in the first bar of a newly started trading system ?

verdi55 · Mon, 19 Mar 2018 21:00:38 +0000

but never again later, even when the system is “not onmarket” ? So, I would like to open a position immediately after the start of a trading system (in demo mode), only once at the end of the first bar. I tried : ONCE flag = 0 If flag = 0 then buy 1 contract at market flag = 1 endif but unfortunately this does not work and it does not open any position at any time. This works : If not onmarket then buy 1 contract at market endif It buys 1 contract immediately after the start of the system, at the end of the first bar. But this code would also buy later on again, when there is no position open, not only once. The simplest code ONCE buy 1 contract at market is not allowed and recognized as a syntax error. My rationale is that I would like to restart a trading system that has been stopped erroneously, by some external interaction or error, for example. So, when I know that the normal regular system is currently long, but the long position has been erroneously closed because the system stopped, I would like to restart the system and open this long position immediately at the end of the first bar and treat it as the regular long position that was open before. But of course, such a “manual” position should never be opened later on again, and the system should just continue on its regular path. Has anyone any ideas ? Or do I not see the simplest solution ?

of course, I just meant your concept.

You could say :

If date = 20180320 and TIME = 073500 then
buy 1 contract at market
endif

If date = 20180320 and TIME = 073500 then

buy 1 contract at market

endif

to open a position in a system in the 1 minute chart that was started between 7:34 and 7:35 and will have its first bar at 7:35.

Agree ?

Problem may be if you start a system out of hours and there is accidentally no bar at 7:35, no position will be opened.

So, the method with prelaodbars and barindex may be more reliable.

I have posted a system that opens a position exactly at last minute of opened markets.

As far I understand you want a code that opens a position exactly when it is activated and then controls the trade itself. I think is a very powerful tool for manual trading as default style of trading.

By the way, once I test a code that opens stop and limit orders symulstaniously. Then the first try I had a copy paste problem the result was that it opened a trade “exactly at the moment of activation not at the end of the bar closing. That means for me that prorealtime runs the systems at the moment of activation like running the code at every closing bar.

let us know your progress

It would be a pain having to open the System in the coding window and then enter date and starting Time then back to the system running window then delete the old system (without current date and time) and also you would lose your Performance History. Or am I misunderstanding?

Yes Leo I am also thinking this Snippet could form part as a semi-manual entry, auto close trading Strategy.

Good Work Verdi55

I use this:

If not onmarket then
buy 1 contract at market
endif

// Set Stops and Profits

IF StrategyProfit <> 0 then
QUIT
ENDIF

If not onmarket then

buy 1 contract at market

endif

// Set Stops and Profits

IF StrategyProfit <> 0 then

QUIT

ENDIF

Thanks. Or maybe we could say :

If barindex = tradeindex then
flag = 1
endif

If not onmarket and flag = 0 then
buy 1 contract at market
endif

If barindex = tradeindex then

flag = 1

endif

If not onmarket and flag = 0 then

buy 1 contract at market

endif

This would definitely open only 1 position, even if the result of the first position is accidentally zero.

Here my code. I was not able to open a position exactly when the system is activated rather it opens a position in the next bar.

My code is thought to be a standard

DEFPARAM CumulateOrders = false // Cumulating positions deactivated
DEFPARAM PreLoadBars = 100 //cargar informacion

IF NOT ShortOnMarket THEN
BUY 1 CONTRACTS AT MARKET
SET STOP pLOSS 15
SET TARGET pPROFIT 30
ENDIF
MySAR= SAR[0.005,0.01,0.7]
IF shortonmarket then
IF close crosses under MySAR THEN
EXITSHORT AT MARKET
ENDIF

IF CLOSE-POSITIONPRICE > 7*PIPSIZE THEN
SET STOP pLOSS 1
ENDIF
ENDIF

IF shortonmarket[1] and not shortonmarket then
QUIT
ENDIF

DEFPARAM CumulateOrders = false // Cumulating positions deactivated

DEFPARAM PreLoadBars = 100 //cargar informacion

IF NOT ShortOnMarket THEN

BUY 1 CONTRACTS AT MARKET

SET STOP pLOSS 15

SET TARGET pPROFIT 30

ENDIF

MySAR= SAR[0.005,0.01,0.7]

IF shortonmarket then

IF close crosses under MySAR THEN

EXITSHORT AT MARKET

ENDIF

IF CLOSE-POSITIONPRICE > 7*PIPSIZE THEN

SET STOP pLOSS 1

ENDIF

IF shortonmarket[1] and not shortonmarket then

QUIT

ENDIF

manual trade for me.

I do not have any clue what are you talking about or why you are posting so weird videos.

So you were being sarcastic… I got it.

Anyway.

what about the code I posted? What’s your opinion apart of my costant values?
