Thank you very much

Thats an issue with the higher builds of TWS and the legacy DDE interface; theres a thread on it a couple days back.?
Try TWS v972:?

Yes if you press Ctrl-Alt-= simultaneously on your keyboard.?

Perhaps because my balance is below usd2000. ?Seems strange that I can get live data from paper trader using api but can’t transmit an order.

Perhaps you're on IB's "LiTE" plan, which does not allow placing trades via the API (unlike the "Pro" plan). See?

In your TWS/Gateway's API configuration, you need to ensure that the "Enable DDE clients" checkbox is on and the "Read-Only API" checkbox is off. I suspect that it is set-up differently on your TWS.?

Hi

I successfully got this spreadsheet working and trading hands free about 1 year ago.? It is a simple program that looks at the last 18 seconds of tick data and then if there is a movement up, it places a sell bracket order with a? stop and a take profit.? Similarly, if there is a move down it places a buy bracket order.? I only used it in paper trading account, but the purpose was to see what i could get done after mastering how to program a bracket order

?

It worked perfectly 1 year ago.? Now it connects to to market data, but the orders do not fire.? I cannot seem to place a simple buy or sell order or a bracket order that connects and fires through the API.

I have downoaded the stable version of TWS for windows 32 Bit
I have downloaded the API software.

Even when i use the sample dde sheet from from IB, i can get market data, but i cannot fire a simple order.

Please if someone has the time, could they open their paper trading account and try out my spreadsheet.

First thing to do is change name to your paper trading account name in my spreadsheet
Then, hit Reset All And Create Futures Ticker button

Then start timer and wait for 18 seconds for 18 seconds of data to accumulate

THen Hit Handbrake off button.

I just want to see if it actually places orders.

My account is only funded to about USD1000 at the moment, could this be a reason?

If not what am i doing wrong

Cheers

reqmktdata, reqpnl etc.?
is there a way to know what all I have subscribed to via API calls??

one way is to put the logic in my API but would be nice if data exists on server somewhere.

Happy to say solved this last night, it was a thread blocking issue.

Is it somehow possible to see in the TWS how many market data lines one has subscribed to?

The Release Notes are always linked from the download page?
I think the most recent (v979) are still being written up. Its not necessary to upgrade the API though, unless theres a specific feature you're interested in using. Was there a particular feature you had a question about, or were you just curious about whats new??

The reqCompletedOrders function is for both cancelled and filled orders (and partially filled) that are no longer active. totalQuantity is for the size of the part of the order which didn't fill, whereas filledQuantity would be for the size of the filled part. So if the order filled completely you'd have totalQuantity=0 and filledQuantity=filled size.?

the thing thats confusing to me is that I dont actually want to change anything, just reset the limit at which IB places the trade. However the Order does not tell us the current limit price, since its of type SNAP PRIM.?

Thanks for the reply, even the error callback in EWrapper gets blocked. I am leaning towards option 3 of yours, but I want to know how the API was able to block everything from EWrapper .......

Although IB does occasionally break TWS or the api libraries this kind of situation is almost always an issue in the client app.

Since you have multiple threads with an intermittent failure a race condition is a likely suspect.

I don't use the C# libraries so I don't have specific help on what to look for inside the library.

Given that the TWS log shows the data is sent then:
1) The tws library has stopped reading the socket
2) The tws library has stopped making callbacks
3) A callback never returns and prevents future callbacks from being called

There may be other possibilities but you get the idea. Since data arrives during shutdown you might look for any threads that get released during shutdown (but were previously stalled).

You can modify an order by calling placeOrder with the same order id. Fill in all the fields the same as the original order except the ones you want to change.

Some changes are allowed and some aren't. You'll probably have to experiment to see if you can change the price for this order type.

This seems like one of the newer api functions so there might not be too many people using it yet.

I think your best bet is to contact IB Api support if you haven't seen a reply by now.
