【Quant】TQuant Lab Aroon Up Down Trading Strategy
Deploy Aroon Up Down trading strategy on TQuant Lab.
Highlight
- Difficulty: ★☆☆☆☆
- Using Aroon-up、Arron-down as indicators to trigger the action of buy and sell.
- This article is revised from Aroon Up Down Strategy via TQuant Lab.
Perface
Aroon Indicator, developed by Tushar Chande in 1995, is typically for measuring market tendency. It consists of two lines — Aroon Up and Aroon Down.
- Aroon Up：((Number of periods — Number of periods since highest high) / Number of periods) * 100
This indicator measures the periods since the highest price (high point) occurred within the selected period. - Aroon Down：((Number of periods — Number of periods since lowest low) / Number of periods) * 100
This indicator measures the periods since the lowest price (low point) occurred within the selected period.
The Aroon Up indicator measures the strength and time since the highest price within a given period (usually 25 periods). In contrast, the Aroon Down indicator measures the strength and time since the lowest price within the same period. These indicators are expressed as percentages and range from 0% to 100%.
The crossover of the Aroon Up and Aroon Down lines can be used to signal potential changes in trend direction. For example, when Aroon Up crosses above Aroon Down, it might be seen as a bullish signal, indicating a potential shift towards an upward trend. Conversely, when Aroon Down crosses above Aroon Up, it could be interpreted as a bearish signal, suggesting a potential shift towards a downward trend.
Aroon Up Down Trading Strategy
When Aroon Up is greater than 80 and Aroon Down is lesser than 45, which represents a bullish trend. We consider it a buying signal and will acquire one unit at tomorrow’s opening price.
When Aroon Up is lesser than 45, Aroon Down is greater than 55, and the gap of two indicators is greater than 15, we regard it as a selling signal and sell the holding position at tomorrow’s opening price.
When Aroon Up is greater than 55, Aroon Down is lesser 45, the gap between the two indicators is greater than 15, our invested amount isn’t greater than 20% principal, and we still have plentiful cash. We will acquire one more unit at tomorrow’s opening price.
Programming environment and Module required
MacOS and Jupyter Notebook is used as editor
Data and Module Import
The back testing time period is between 2018/01/01 to 2020/12/31, and we take Hon Hai Precision Industry(2317), Compal Electronics(2324), Yageo Corporation(2327), TSMC(2330), Synnex(2347), Acer(2353), FTC(2354), ASUS(2357)、Realtek(2379), Quanta(2382), and Advantech(2395) to construct the portfolio and compare the performance of portfolio with the benchmark—— Total. Return Index(IR0001), .

from zipline.pipeline.mixins import LatestMixin
from zipline.master import run_pipelineSetting Benchmark
First, We load the bundle which we just ingest above, and set return index(coid : IR0001) as benchmark.
bundle = bundles.load('tquant')
ir0001_asset = bundle.asset_finder.lookup_symbol('IR0001',as_of_date = None)Create Pipeline function
Pipeline() enables users to quickly process multiple assets’ trading-related data. In today’s article, we use it to process:
- The calculation of Aroon-up, Aroon-down (built-in factor:
Aroon)
def make_pipeline():
curr_price = EquityPricing.close.latest
alroon = Aroon(inputs = [EquityPricing.low, EquityPricing.high], window_length=25, mask = curr_price < 5000)
up, down = alroon.up, alroon.downreturn Pipeline(
columns = {
'up': up,
'down': down,
'curr_price': curr_price,},
screen = ~StaticAssets([ir0001_asset])
)Creating Initialize Function
inintialize enables users to set up the trading environment at the beginning of the back test period. In this article, we set up:
- Slippage
- Commission
- Set the return index as the benchmark.
- Attach
Pipline()function into back testing.
def initialize(context):
set_slippage(slippage.VolumeShareSlippage())
set_commission(commission.PerShare(cost=0.00285))
set_benchmark(symbol('IR0001'))
attach_pipeline(make_pipeline(), 'mystrategy')Creating handle_date Function
handle_data is used to process data and make orders daily.
Default trading signals buy, sellare False
buy: When today’s indicators matches the buy-in condition, generates buying signal and toggles the boolean value to True。sell: When today’s indicators matches the sell-out condition, generates selling signal and toggles the boolean value to True。

passCreating Analyze Function
analyzefunction is mostly used to visualize the result of backtesting. Since today’s practice will use pyfolio to achieve visualization, we just leave it empty.
def analyze(context, perf):
passRun Algorithms
We expliot run_algorithm() to execute our strategy. The backtesting time period is set between 2018-01-01 to 2020–12–31. The data bundle we use is tquant. We assume the initial capital base is 1,000,000. The output of run_algorithm(), which is results, contains information on daily performance and trading receipts.
results = run_algorithm(
start = pd.Timestamp('2018-01-01', tz='UTC'),
end = pd.Timestamp('2020-12-31', tz ='UTC'),
initialize=initialize,
bundle='tquant',
analyze=analyze,
capital_base=10e6,
handle_data = handle_data
)
results
Visualization
Before process visualization, we need to seperate the data of results to three part:
- returns
- positions
- transactions
from pyfolio.utils import extract_rets_pos_txn_from_zipline
returns, positions, transactions = extract_rets_pos_txn_from_zipline(results)# 時區標準化
returns.index = returns.index.tz_localize(None).tz_localize('UTC')
positions.index = positions.index.tz_localize(None).tz_localize('UTC')
transactions.index = transactions.index.tz_localize(None).tz_localize('UTC')
benchmark_rets.index = benchmark_rets.index.tz_localize(None).tz_localize('UTC')Lastly, pyfolio.tears.create_full_tear_sheet can generate multiple tables and charts to help you evaluate the portfolio’s performance.
pyfolio.tears.create_full_tear_sheet(returns=returns,
positions=positions,
transactions=transactions,
benchmark_rets=benchmark_rets)Source Code
Conclusion
Today’s practice uses TQuant Lab to deploy the Aroon Up Down trading strategy. With the engagement of TQuant Lab, the difficulty and complexity of the program have significantly reduced. TQuant Lab provides more detailed parameters and indicators for users to create a meticulous trading strategy.
