Examples: marketPricePause() and marketPriceResume()

[peervm]

Hi,

Can you provide working examples of marketPricePause() and marketPriceResume() please.

I am unable to make the call as per the documentation and the stubs below don't help much.

Thanks, Peer

Boost.Python.ArgumentError: Python argument types in Pyrfa.marketPriceResume(Pyrfa) did not match C++ signature: marketPriceResume(class Pyrfa {lvalue}, class boost::python::api::object)

Hello Peer,

Pyrfa.marketPricePause(symbols) and Pyrfa.marketPriceResume(symbols)

requires the input parameter as strings for example: p.marketPricePause("JPY=") p.marketPriceResume("JPY=")

you can also pause/resume multiple rics using "," for example

p.marketPricePause("JPY=,EUR=")

Best regards, Ukrit H.

There is a working example on GitHub https://github.com/devcartel/pyrfa/blob/master/examples/conflate.py

Thanks guys. The conflate.py example has pauseAll() and resumeAll() which works fine for me.

I'm using 8.1.0 on Python 3.6 win64 but this code doesn't work; p.marketPricePause("JPY=") p.marketPriceResume("JPY=") where p is an instance of the pyrfa.pyrfa.Pyrfa class.

It says method signature error; did not match C++ signature: marketPriceResume(class Pyrfa {lvalue}, class boost::python::api::object)

[peervm]

I can see the signature looks the for all methods;

• def marketPriceRequest(self, Pyrfa, *args, **kwargs):
• def marketPriceResume(self, Pyrfa, *args, **kwargs):
• def marketPricePause(self, Pyrfa, *args, **kwargs):

Expected usage:

• p.marketPriceRequest("JPY=") #Works fine
• p.marketPriceResume("JPY=") #Fails
• p.marketPricePause("JPY=") #Fails

@peervm Can you check the PyRFA version on your machine? Looks like you are loading older version of PyRFA. PyRFA supports pause and resume from version 8.0.0.1.

@peervm We just did a test on Python 3.6 windows 64 and it works fine.

Result:

Try with below code:

import pyrfa
exec(open('./utils/every.py').read())

p = pyrfa.Pyrfa()
p.createConfigDb("./pyrfa.cfg")
p.acquireSession("Session1")
p.createOMMConsumer()
p.login()
p.directoryRequest()
p.dictionaryRequest()
p.marketPriceRequest("JPY=")
p.dispatchEventQueue(1000)
p.marketPricePause("JPY=")

def getConflatedUpdate():
    p.marketPriceResume("JPY=")
    updates = p.dispatchEventQueue(10)
    p.marketPricePause("JPY=")
    if updates:
        print("")
        for u in updates:
            print(u['SERVICE'] + " - " + u['RIC'])
            for k,v in u.items():
                if type(v) is float:
                    print("%15s %g" % (k,v))
                else:
                    print("%15s %s" % (k,v))
            print("")

loop = every(10, getConflatedUpdate)
end = False
try:
    while not end:
        pass
except KeyboardInterrupt:
    loop.stop()
    end = True

Installing RFA libraries on win7 machine installs into difference and confusing paths and this caused a conflict.

• C:\Program Files\Reuters\rfa\8.0.1 #64bit version
• C:\Program Files (x86)\Reuters\rfa7 #32bit version

I haven't fixed the issue locally yet, but it is almost certainly the root cause.

Thanks for your assistance and amazing response time.

Got everything working now. But just for future reference, another mistake I made was to use snapshot mode. Obviously pause\resume only works for setInteractionType("stream").
