Description

the error is : AttributeError: 'mexc' object has no attribute 'fapiPrivate_post_leverage'

i made script in python for Futures mexc with a leverage of 100 x the purchase order and the termination of the deal Market taking profits on a profit of 0.01% as an example In the event that I entered number 1 in the terminal script, I will execute a purchase order or wait to take profits, or enter number 3 to end the transaction with a market order

the error is : AttributeError: 'mexc' object has no attribute 'fapiPrivate_post_leverage'

and if you have anything to edit or improve script im need help

Code

import ccxt

api_key = 'api_key' secret = 'secret' leverage = 100 symbol = 'BTC/USDT' # Bitcoin trading pair take_profit_percentage = 0.01 # 0.01% profit

exchange = ccxt.mexc({ # Assuming exchange is Binance 'apiKey': api_key, 'secret': secret, 'enableRateLimit': True, 'options': { 'defaultType': 'future' } })

def create_long_order(): data = exchange.fapiPrivate_post_leverage({ 'symbol': symbol.replace('/', ''), 'leverage': leverage })

market_price = exchange.fetch_ticker(symbol)['last']
balance_usdt = exchange.fetch_balance()['total']['USDT']  # Fetch your USDT balance
amount_btc = balance_usdt / market_price  # Use your total USDT to buy BTC
order = exchange.create_market_buy_order(symbol, amount_btc)
print('Buy order created at market price:', market_price)
return order

def close_order_at_market(): balance = exchange.fetch_balance()['total']['BTC'] order = exchange.create_market_sell_order(symbol, balance) print('Order closed at market price') return order

while True: action = input("Enter 1 to execute a buy order, 3 to close the order at market price: ") if action == '1': order = create_long_order() while True: order_info = exchange.fetch_order(order['id'], symbol) if order_info['status'] == 'closed': print('Order closed with a profit of 0.01%') break elif float(exchange.fetch_ticker(symbol)['last']) >= float(order['info']['price']) * (1 + take_profit_percentage): # Fetch the latest price close_order = close_order_at_market() break elif action == '3': close_order = close_order_at_market() break

Hello @jejoj, fapiPrivate_post_leverage is not an implicit endpoint from Mexc., it belongs to Binance so I think you might be mixing some different things in your script.

carlosmiei commented 1 year ago

@jejoj If you want to set the leverage at Mexc you can use the unified set_leverage method.

my code after editing `import ccxt

market_price = exchange.fetch_ticker(symbol)['last']
balance_usdt = exchange.fetch_balance()['total']['USDT']  # Fetch your USDT balance

@jejoj first and foremost, never post your keys publicly, keep them in secret.

Please, read this carefully, literally to a word:

Second, please, read the signature of the set_leverage() method, it accepts a number of arguments instead of a dictionary:

Check the implementation of MEXC for more info:

For MEXC that would look like:

    data = exchange.set_leverage(leverage, symbol, {
        'openType': 1,  # Use isolated margin
        'positionType': 1,  # Use long position
    })

We highly recommend reading the entire Manual from top to bottom, it will really save your time (we cannot write the code for you and we cannot fix all the code in the world since this library is used by thousands of users). The key to using this library efficiently is reading the documentation very carefully (you have to get used to a lot of reading as noted in the FAQ):

Also, check the examples here:

ok thanks i will search on it

@jejoj feel free to reopen this issue or just ask further questions here if any, closing it for now.

@jejoj if you want to trade contracts instead of spot markets, then you have to specify a correct contract symbol which is SOL/USDT:USDT (Not SOL/USDT which is for spot markets). Please, read the manual once again:
