Symbol Mapping

[NinjaTrader_Ray]

Please check Tools > Instrument Manager, double click on ES, click on Misc tab, under symbol mapping for "External" make sure you see "ES" excluding quotations.

It reads ES|09-08. That is how I set it up so that it would continue trading the September contract until I roll it over to the new December contract. Otherwise my swing positions would be a mess during rollover.

Not sure if this will work but can you try:

Map=EMDU08,ES 09-08

[tmd]

Did you mean "Map=EMDU08,ES|09-08"?

[tmd]

Never mind, TS does not allow | in the workspace name. I will give it a try and let you know.

[tmd]

The ES 09-08 designation does not work. It caused a rejected order from another strategy that trades the ES contract even though it was in a different workspace. This makes me think that mapping a contract in one workspace has an effect on another workspace even if they have unique names. Any other suggestions?

[NinjaTrader_Ray]

What if you just put in "ES" for the "External" map for the ES instrument? If you try this, restart NT afer you make the change before you try it.

[NinjaTrader_Ray]

Or, leave the map as you had it before "ES|09-08" and in the workspace try:

"Map=EMDU08,@ES"

[tmd]

I will give it a try. Can you please respond to whether mapping in one workspace affects another workspace even if it is not mapped. Thank you.

The map in NT is what is used anytime we parse an incoming email from TS.

TS send us a symbol (indpendant of workspace name) of the symbol charted. We take this information and use the map set in NT to properly route to the correct instrument.

[tmd]

So you are saying that using the Map=xxx,xxx in naming in a workspace, also affects other workspaces using the same symbol regardless of whether each workspace has a unique name and only one workspace has the Map=xxx,xxx in it. Is that correct?

[NinjaTrader_Ray]

That's not what I am saying.

What I am saying is that a workspace mapping has no affect on other sybmols. More to the point, a workspace name is irrelevant.

[tmd]

From my recent experience, it seems to have an affect on other symbols because the workspace mapping setup you gave me yesterday, Map=EMDU08,ES 09-08, appears to have caused me to have a rejected trade in a different workspace that did not have any Map=xxx,xxx in the workspace name. The NT Log shows this rejection was due to the ES 09-08 designation. It reads "...Rejected Instrument='ES 09-08' ". I have a couple years of experience trading the ES through the email interface and this is the first time I can remember having a rejected trade. So I have no other conclusion to make other than the Map=xxx,xxx designation does affect other workspaces even if they do not have the Map=xxx,xxx in the name. I can email my log if you'd like to see it.

The workspace name has no affect.
The change in mapping in the Instrument Manager --> This is what had the affect.

[tmd]

I did not change the mapping in the Instrument Manager. The last time I changed it was during rollover in June from the June to the September contract. The external mapping in the Instrument Manager is ES|09-08. Your literature/forum replies also show this is a correct way to map. And from my experience, I've never had a rejected order using the external map ES|09-08. Only when I added the Map=EMDU08,ES 09-08 to my other workspace did I receive a rejection. When I removed the Map=... from my other workspace, my stategy in the workspace that never had a Map=... initiated a trade as before without a problem.
