Final work around / resolution

Taking the standard debugging approach of removing complexity until  it worked and then adding things back in until it stopped I found that the failure point occurred when I added the comment string parameter.   It worked fine with the stopPips and takeProfitPips which I previously thought was causing the issue.   I have not tried to figure out exactly what it was about my comment string the server had a problem with and there is no documentation I can find about the limits of what can be put in a comment string.   This documentation would be very helpful.

RE: Modified for null stop limit and null take profit and same order worked.

March-31 13:37

I modified the code to set the stopPips and ProfitPips to null and the order executed as expected but since the stop limit  and target price are null the order to add missing stop limits had to kick in to modify the position to add them.   There is some extra latency when used this way that leaves the position exposed to greater risk than desired.    Next I will modify to try just setting the profitPips and see if it still works. 

I modified the code From (FAILS):

      var orderResult = PlaceLimitOrder(TradeType.Sell, Symbol, orderVolume, targetLimitPrice, StratLabel, stopPips, profitPips, expireTime, cmt);

TO: (WORKS)
      var orderResult = PlaceLimitOrder(TradeType.Sell, Symbol, orderVolume, targetLimitPrice, StratLabel, null, null, expireTime, null);

I have been using limit orders for TradeType.Buy successfully for quite some time but am struggling with the .Sell due to a "INVALID_REQUEST" message as shown below.    The same code runs fine in a backtest but fails when running live in a virtual account.   From the cAlgo journal it looks like it sent the order to the server with the right set of parameters or at least about what I would have expected. 

Snippet of Code 

 var orderResult = PlaceLimitOrder(TradeType.Sell, Symbol, orderVolume, targetLimitPrice, StratLabel, stopPips, profitPips, expireTime, cmt);
 

Can anybody see what I am doing wrong?

March-31 - Trade result is showing "Error: TechnicalError"

I modified the SL and take profit to require a Minimum of 1 Pip in the PlaceLimitOrderCall.  Also converted them to Integer values since that was shown in the examples.  I am now printing out the TradeResult and get the following Error:

 L527: 2015-03-31 18:54:07.628: OrderResult=TradeResult (Error: TechnicalError)

Request:   When the server rejects and order it would be nice to print out all the Order parameters the server thinks it rejected and would be even better if we got an indication of which parameters the server finds unsuitable. 

For the same Trade the Journal is still showing:

I agree with this as a feature request

I have nearly identical requirements.   It seems like this should be a feature built into the application.   Otherwise it makes it difficult to run multiple copies with different configurations.

I would have some utility classes such as   public class parsedRow which I would like to move into separate C# source members from my main cbot.  I do not have visual studio installed and want to work only inside of calgo.   How do I add a reference to an extra C# file to the cBot directly without having to convert it to a DLL.  EG:   In  Lua I can use require "filename"   in F# I can do something similar.

Is there still a need to Importing external signal files?

see:  /algos/cbots/show/588  and /algos/cbots/show/591  I have also written the portion which does the import and executes trades based on external signals.   If others will find it of value then let me know and I can post it as a new CBot.  It takes quite a bit of extra effort to package things for external consumption but if there is sufficient demand I will do so.  Thanks Joe E.

I too would like this functionality of Running CAlgo as a Library from my larger C# application

I would also like the functionality of referencing  CAlgo as a loaded library rather than running it as a separate application.   For me the more important aspect is the ability to auto-start the system,  auto log in and debug easily all inside of visual studio.     Testing from inside of CAlgo is cumbersome and quite often forces me back to hand writing "Print" statements.

How to Convert MarketSeries.TickVolume() to Transaction Volume?

IN my code  /algos/cbots/show/591 I am using a line  MarketSeries.TickVolume.Last(1)  But this doesn't seem quite right. I don't want tick volume from   MarketSeries.TickVolume.Last(1).    I want actual units transacted.  Since any tick could represent a value from a fractional lot to several lots it seems that there is a huge difference in the actual value of money transacted for any tick move.    I think it makes more sense to record total units traded during the bar.      The theory is that  200 million $ traded during a bar that dropped 10 pips is more meaningful as momentum input than  $2000 traded with the same drop during the same duration.      I would greatly appreciate help doing this conversion.

The volume reading in the market snapshot tools is in what units. For example, a volume reading of 1424 in a EURUSD 15m chart is what?

Thanks

I Think your volume level will always return 0 in the output field.        I have published something similar at /algos/cbots/show/591  but I don't want tick volume from   MarketSeries.TickVolume.Last(1).    I want actual units transacted.  Since any tick could represent a value from a fractional lot to several lots it seems that there is a huge difference in the actual value of money transacted for any tick move.    I think it makes more sense to record total units traded during the bar.      The theory is that a 200 million $ traded during a bar that dropped 10 pips is more meaningful as momentum input than  2000 traded with the same drop during the same duration.

Hi All,

Is it possible to download the backtest data to an external format through the platform?

Essentially I'm trying to get the backtest data in a format such as CSV to run through an external system to then feed back into an indicator.

Thanks.
