Smart Caching
Your computer cannot calculate without data. Because data is stored
on your data vendor's server, data speed is limited by the speed
of your connection to their servers. In effect, the Internet is
the bottleneck of your calculations. This problem is especially
severe for tick data because most commonly traded instruments carry
a tremendous amount of tick data.
NeoTicker® has a sophisticated caching mechanism to handle
tick data. Once tick data has been retrieved from data vendor, it
is cached locally on your hard drive. So calculations that require
the same data do not have to re-download the data.
Caching mechanism is smart. You have options to control how data
holes in cache can be back filled with data vendor data. By downloading
only the required data, NeoTicker® significantly reduces the
need to access Internet for data.
Bid Ask Data Support
Efficiency enables NeoTicker® to handle bid ask data as if
they are regular tick data. NeoTicker® can cache bid and ask
data so you can use historical bid ask data in your analysis, including
indicator calculation.
Tick Precise Indicators
NeoTicker® features a number of indicators utilizing tick level
analysis to showcase what can be done when you have complete access
to historical bid/ask/trade data. For example, TP BidAskTrade and
other TP indicators are the only indicators in the market today
enabling users to measure the breadth of price actions, both in
real-time and in historical data. Thus research on their significance
can be accomplished easily.
Historical Bars from Ticks
All data vendors clean up their historical tick data to remove
bad trades, etc. In a sense, they are doing a service by providing
clean data. However, clean data is undesirable for users who expect
100% consistency between historical and real-time calculations.
When you use clean historical data to test indicators and trading
systems, there is no guarantee the testing result has any relevancy
to real-time performance. Worst, because you cannot control when
and how data vendors clean up the data, each run of indicators and
trading systems can yield different results. Testing will be difficult
to carry out.
Two features of NeoTicker® solve this problem - smart caching
of tick data and reconstruction of historical bars from ticks.
We have seen how smart caching can improve performance. Caching
has an additional advantage - data vendors cannot touch the data.
Once stored on your hard drive, the ticks are the ultimate stable
and consistent data source.
NeoTicker® charts have the ability to reconstruct historical
bars from ticks with tick replay. During tick replay, tick files
are read and ticks are used to reconstruct historical bars, just
like real-time. Indicators are triggered on a tick-by-tick basis
for recalculations. Combined with locally stored tick data, the
resulting chart will be identical to what you see in real-time.
Only with NeoTicker® technology ensures you 100% historical
and real-time calculation consistency at tick level.
