Working with oracles

Querrying oracles:

import pywaves as pw

oracle = pw.Oracle(oracleAddress = '3P4PCxsJqMzQBALo8zANHtBDZRRquobHQp7')
# getting all data entries for an oracle
print(oracle.getData())
# getting data for a specific key of an oracle

tAddress = pw.Address(seed = "test test test", pywaves = config)

address = pw.Address(seed = "test test test")
print(tAddress.address)
print(address.address)
print(tAddress.address)

Playing with Waves Matcher node (DEX):

import pywaves as pw

# set Matcher node to use
pw.setMatcher(node = 'http://127.0.0.1:6886')

# post a buy order

WCT_Incent = pw.AssetPair(WCT, Incent)
myOrder = myAddress.sell(assetPair = WCT_Incent, amount = 100e8, price = 25e8)

# post a buy order using Waves as price asset
BTC = pw.Asset('4ZzED8WJXsvuo2MEm2BmZ87Azw8Sx7TVC6ufSUA5LyTV')
BTC_WAVES = pw.AssetPair(BTC, pw.WAVES)
myOrder = myAddress.buy(assetPair = BTC_WAVES, amount = 1e8, price = 50e8)

# cancel an order
myOrder.cancel()
# or
myAddress.cancelOrder(assetPair, myOrder)

Getting Market Data from Waves Data Feed (WDF):

import pywaves as pw

# set the asset pair
WAVES_BTC = pw.AssetPair(pw.WAVES, pw.BTC)

# get last price and volume
print("%s %s" % (WAVES_BTC.last(), WAVES_BTC.volume()))

# get ticker
ticker = WAVES_BTC.ticker()
print(ticker['24h_open'])
print(ticker['24h_vwap'])

# get last 10 trades
trades = WAVES_BTC.trades(10)
for t in trades:
	print("%s %s %s %s" % (t['buyer'], t['seller'], t['price'], t['amount']))
	
# get last 10 daily OHLCV candles
ohlcv = WAVES_BTC.candles(1440, 10)
for t in ohlcv:
	print("%s %s %s %s %s" % (t['open'], t['high'], t['low'], t['close'], t['volume']))

LPOS

import pywaves as pw

# connect to a local testnet node

Connecting to a different node or chain

PyWaves supports both mainnet and testnet chains. By default, PyWaves connects to the mainnet RPC server at https://nodes.wavesnodes.com. It's possible to specify a different server and chain with the setNode() function
