Matatrader5 for python, market_book_add, market_book_get not working. Please help!

[laiang]

Hello, for Metatrader5 in python, market_book_get is not working. It always print "mt5.market_book_add('EURUSD') failed, error code = (1, 'Success')".

How to solve this problem ?

Thanks

This is the script:

import MetaTrader5 as mt5
import time
# display data on the MetaTrader 5 package
print("MetaTrader5 package author: ",mt5.__author__)
print("MetaTrader5 package version: ",mt5.__version__)
print("")
 
# establish connection to the MetaTrader 5 terminal
if not mt5.initialize():
    print("initialize() failed, error code =",mt5.last_error())
   # shut down connection to the MetaTrader 5 terminal
    mt5.shutdown()
    quit()
 
# subscribe to market depth updates for EURUSD (Depth of Market)
if mt5.market_book_add('EURUSD'):
  # get the market depth data 10 times in a loop
   for i in range(10):
        # get the market depth content (Depth of Market)
        items = mt5.market_book_get('EURUSD')
        # display the entire market depth 'as is' in a single string
        print(items)
        # now display each order separately for more clarity
        if items:
            for it in items:
                # order content
                print(it._asdict())
        # pause for 5 seconds before the next request of the market depth data
        time.sleep(5)
  # cancel the subscription to the market depth updates (Depth of Market)
   mt5.market_book_release('EURUSD')
else:
    print("mt5.market_book_add('EURUSD') failed, error code =",mt5.last_error())
 
# shut down connection to the MetaTrader 5 terminal
mt5.shutdown()

Hello, when I use BTCUSD the script works. May be it's because we are in weekend.

I really wanna understand more about market_book structure. thanks!

This is the script:

Why are thinking it's "not working" when it returns "Success" ?

There is usually not market book orders for Forex symbols. Some brokers provide it for their own market book which is only a small part of the real market.

Thank you! I change the broker and it's working right now. thank you!

Is this "FEATURE" or "BUG by design" of MT5 python ?
If it depends on broker, maybe it should be mentioned on python api documentation.

I can see Depth of Market in MT5 terminal, but unable to retrieve any books of BTCUSD or any cryptos using above code.

mt5.market_book_add('BTCUSD')

always returns False, but last error is (1, 'Success')



Excellent API ;)

@Soewono Effendi #: I can see Depth of Market in MT5 terminal

Where? There is no "Market Depth" in your screenshot! All you see is a convenient tool to help place orders.

This is "Market Depth" ... do you see the difference?

I see, misleading last_error()

Thanks for confirmation.

@Soewono Effendi #: I see, misleading last_error().

It is not misleading because no error occurred. It returned "false" (no market data available). That is not an error.
