Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
bfx-hf-backtest
Advanced tools
This repo provides an interface for executing backtests using either offline data, or a bfx-hf-data-server
instance for historical Bitfinex market data.
To execute a backtest of a trading strategy using historical data, the execOffline
method is provided which will run the strategy against each trade & candle in-order by timestamp:
const HFS = require('bfx-hf-strategy')
const HFBT = require('../')
const EMAStrategy = require('bfx-hf-strategy/examples/ema_cross')
const { Candle } = require('bfx-api-node-models')
const { SYMBOLS, TIME_FRAMES } = require('bfx-hf-util')
const rawCandleData = require('./btc_candle_data.json')
// During real execution, candles can arrive from any market/at any time (if
// sub'ed to multiple time frames); hence, each candle must include its origin
// symbol/time frame pair.
const market = {
symbol: SYMBOLS.BTC_USD,
tf: TIME_FRAMES.ONE_HOUR
}
const candleKey = HFS.candleMarketDataKey(market)
const strat = EMAStrategy(market)
const candles = rawCandleData
.sort((a, b) => a[0] - b[0])
.map(c => ({
...(new Candle(c).toJS()),
...market // attach market data
}))
const run = async () => {
await HFBT.execOffline(strat, {
trades: {},
candles: {
[candleKey]: candles,
}
})
}
try {
run()
} catch (e) {
console.error(e)
}
Online backtests are executed a running bfx-hf-data-server
instance, which will automatically synchronize historical data as needed and pass it to the backtesting logic:
const HFBT = require('../')
const EMAStrategy = require('bfx-hf-strategy/examples/ema_cross')
const { SYMBOLS, TIME_FRAMES } = require('bfx-hf-util')
const now = Date.now()
const market = {
symbol: SYMBOLS.XMR_USD,
tf: TIME_FRAMES.ONE_MINUTE
}
const strat = EMAStrategy(market)
const run = async () => {
await HFBT.execOnline([strat], {
exchange: 'bitfinex',
from: now - (2 * 24 * 60 * 60 * 1000),
to: now,
trades: true,
candles: true,
...market
})
}
try {
run()
} catch (e) {
console.error(e)
}
