Understanding Tick Data

As a data vendor, we focus solely on historical intraday data for traders and institutions to use in strategy development or backtesting. Most traders begin building their strategies using intraday bars which are very useful for prototyping a trading strategy, however, for accurate backtesting and simulating real-world trading profits we always recommend using tick data

What is Tick Data?

Tick data is the highest resolution intraday data and is the sequence of each executed trade or bid/ask quote aggregated from multiple exchanges.

For example, below is a sample of stock tick data for AMZN on April 4, 2018.

(timestamp, price, volume)

2018-04-11 04:00:00:070,1434,5

2018-04-11 04:00:06:245,1431.91,100

2018-04-11 04:00:08:176,1430,1

Types of Tick Data

There are four types of tick data:

Trade tick data - the sequence of executed trades (as shown in the example above)

Bid/Ask (Level 1) data - the NBBO (National Best Bid and Offer) bid/ask quotes

Bid/Ask (Level 2) data - is the NBBO plus each registered dealer’s best bid and offer (ie the full order book)

Bid/Ask (Level 3) data - is only available to NASD member firms and comes with execution and amendment privileges. 

How and Why to Use Tick Data.

The single biggest issue with developing trading strategies on bar data is it always overestimates the profits generated by the strategy. This is due to optimistic assumptions on trade entry and exit prices, many backtesting tools will assume that the trade can be entered close to the bar low or sold close to the high, however this is impossible to know if the only information is open, high, low, close, volume.
When the bid/ask tick data is incorporated into backtesting the strategy can realistically simulate the buying at the bids and selling and at the ask prices. 

Another issue with bar data is that it obscures vital information on the buying or selling since all trading activity is aggregated into a single time-bar. Analyzing tick data can give insights into trading patterns, for example, several large volume trade ticks will likely indicate institutional trading whereas multiple small volume trade ticks can indicate retail involvement.
Tick data can also provide advance signaling of price activity, for example, the widening of the bid/ask spread accompanied by low trading volumes is often a precursor to a technical breakout of resistance/support levels.

Note that in the above examples, both trade tick and bid/ask tick data have been used. Trade tick data is useful in analyzing price trends and trading activity, however, as with bar data, it is difficult to accurately estimate trading profits from pure price activity alone. Therefore, we would recommend performing a backtest simulation using the bid/ask tick data to test actual entry and exit prices on trades. 

Note that Level 2 data can also be purchased and gives extra signaling on future demand and supply, however, it is highly prone to manipulation as participants may place and withdraw large bids or offers to generate false signals.
