RE:

That is interesting - i didn't look at the spec and managed to log on successfully without using SenderSubID AT ALL 

However, i was unable to submit a MarketDataRequest - looks connected 

I'll let you know how it goes for me when i read the manual - lol

Hi everyone

I have some trouble with the cTrader Fix API.
I can't log on.

I send this message:

8=FIX.4.4
9=107
35=A
34=1
49=ctrader.3129678
50=Trade
52=20160720 11:25:01.724
56=CSERVER
98=0
108=30
553=3129678
554=#MyPassword#
10=079

But I get this response: Required tag missing (Field=50)

This is my log-file:

20160720-11:25:01.626 : Connecting to 212.83.157.16 on port 5202
20160720-11:25:01.681 : Connection succeeded

20160720-11:25:06.083 : Session FIX.4.4:ctrader.3129678/Trade->CSERVER disconnecting: Tried to send a reject while not logged on

I attached the files (FIX44.xml and quickfix.cfg config-file) to this message https://yadi.sk/d/AE-Y03J5tTyqp

I tried using SenderSubID (50) in all my messages - i can still log on but i am still unable to subscribe to Market updates (my Symbol is rejected) 

FYI my logon message FIX is as follows - dunno if it helps

8=FIX.4.49=11935=A34=149=icmarkets.xxx=QUOTE52=20160804-19:30:43.69256=cServer98=0108=30141=Y553=xxx554=xxx10=169

One though occurred - TraddingSession Status messages are not documented so i assumed that were not being used 

However i can logon:
8=FIX.4.49=9435=A34=149=cServer52=20160804-19:30:43.77956=icmarkets.xxx57=QUOTE98=0108=30141=Y10=163
