New Features

IDL Indicators

- New object ExtHeap that can be used as a communication tool between an indicator and its nested indicators
- Itself object new method ParentExtHeap for the access of the ExtHeap from the parent indicator
- Heap object new methods –

IntCount : integer returns the number of Int items that are stored within the heap

IntItem (AnIndex : integer, var AName : string, var AValue : integer) : boolean gives the user access to the stored Int items through an enumeration process using AnIndex from 0 to IntCount - 1 to access both the name and value stored within each item

RealCount : integer returns the number of Real items that are stored within the heap

RealItem (AnIndex : integer, var AName : string, var AValue : integer) : boolean gives the user access to the stored Real items through an enumeration process using AnIndex from 0 to RealCount - 1 to access both the name and value stored within each item

Formula Indicators

- New objects with functions to match the IDL equivalent – heap, pheap, extheap, parentextheap, gheap
- Listing of introductory functions for these heap objects, more will be added over time,

Allocate (size : integer)
Value (slot : integer) : double
SetValue (condition : boolean, slot : integer, value : double)
Real (name : string) : double
SetReal (condition : boolean, name : string, value : double)
Int (name : string) : integer
SetInt (condition : boolean, name : string, value : integer)

All functions sharing the same name as the IDL counterpart works in about the same way.

e.g. you can assign a value using heap.setreal (true, "name", data1) and obtain the stored value using heap.real ("name")

The parameter condition needs to be true for the various set functions to assign values to the heap item. This gives you the ability to control if value is to be assigned to the heap or not.

Misc

- Continuous Contract Table Editor added Clear All button
- Various export commands added support of the new 1 million+ rows limit in Microsoft Excel 2007

Bug Fixes

- Time and Sales export to Excel printing bid/ask data as type -99, which is designated for bad sequence data. Bids are now reported as type 10 and Asks are now reported as type 20
- Time and Sales export to Excel now straightly duplicate what is shown in the window into Excel
- Drawing tools – Support/Resistance, Fib Price 2 Points, Fib Price 3 Points, when used in a chart with log scale, display of price level labels wrongly and inconsistently when the chart is rescaled or when the drawing objects are moved
- Continuous Contract Table Editor sometimes not responding to clicks on the listing area if there is only 1 entry in the table

Notes

- Build 58 and 59 are released for internal testing only
- documentation update will be done in next release

New Features

- Script Editor > Indicator Specification Window > Visual Tab can now add/insert/delete plot series through a new popup menu
- Function Window general popup menu added the command Print Window
- indicator formula now support access to parameters by name with the new function param (name)
- System Performance Report > all reports using time partition including Position P/L by Time, Position Winning% by Time, Order Placement Distribution, etc. now include viewing by 10, 15, 20, 30 Minutes
- Account Manager > Order Confirmation, Open Orders, Processed Orders all added Date column
- Disk Cache Editor added ability to block users from saving the cache data if it contains bad date/time entries

Bug Fixes

- Indicator Setup window Use Depth property spelling incorrect
- accepting NaN (not a number), -INF, +INF as indicator results can lead to random crash
- Indicator set to disable can interfere with normal operation of a real-time streaming chart. Introduced bug from the fill by tick mechanism introduced several releases ago
- When NeoTicker Time Zone is set to GMT, GMT+n, and that a chart is using GMT+m, where n < m, then at a particular time period where there is a different in day reporting by the 2 time zone, the time chart data loading will miss a portion of data
- When editing minute or tick data using Disk Cache Editor, with Gen Daily option enabled, pressing the Save button to save the cache data, can lead to corruption of the EOD cache data file due to interference from the real-time data source on the daily level data fields. In turn these corrupted daily data files can destablize NeoTicker when they are used by the charts or quote formulas.
- Disk Cache Editor displaying cache data with bad date/time stamp can lead to crash

New Features

- maintenance release, no new features

Bug Fixes

- Continuous Contract Manager memory corruption problem causing failure to recognize continuous symbols properly
- On some rare conditions (e.g. upon creation of a new chart after first start up) may trigger NeoTicker to check if the user wanted to go offline mode on next reconnection, can causes odd problems like going offline instead of reconnecting to active data feed (including Sim Server)
- Time Chart Tick Replay over Last N Days would continuously trying to load data if the number of days requested to replay is beyond the starting date time of the currently loaded chart data series. Pressing the abort button can stop the process.
- Time Chart Time Axis Labels when displayed in 2 lines, some windows sizing and monitor configuration can cause the second line to show the upper part of the letters only.

New Features

Continuous Contract Manager
- Table Driven option enabled
- now compatible with Sim Server during replay through contract switch over time

Sim Server
- reconnection reliability improved
- contract roll over time now sync with historical data loading, at GMT midnight

Account Manager
- Live Systems tab now maintains the last scroll to position and user selection.

Time and Sales

Other
- Formula Editor new option to save the last position and size

- System Performance Viewer now support thumb tracking across all listing tables
- Command line option -OFFLINE added for NeoTicker to start up in offline mode
- New formula generic function SafeDiv (Num, Div, Err)
- New IQFeed data server included

Bug Fixes

- Continuous Contract symbols not properly recognized when pulling daily data from eSignal
- After disconnect, if user modify a time chart by adding / deleting data series, and then reconnect to real-time data service or sim server, the time chart may not be able to stream updates to the proper data series
- Sim Server failed to load EOD data after failure to initialize tick stream file
- Sim Server does not load the last day of tick data for replay if the ending time is set to any time before GMT noon
- double processing on system performance position query if editing of a query field is not completed while the Start button is pressed
- system performance position query on a completely blank query can ocassionally cause a crash
- When an indicator is set to update on bar completion, having more than 1 link, and that the primary link is a data series, the indicator would fail to update on some special initial conditions. Similar problem can manifest on tick replay all days
- Quote Setup window > Format tab > Sig. Fig changes to the digits not applied properly to the quote window
- Data series loading used the NeoTicker global time zone, as oppose to take into account the user specified locale in the time chart, quote formula environment, etc., leading to missing part of the data series in the first day of the chart
