# New MT4 beta and assorted upgrades

Published 2026-08-10

**If you are a client** you should have already received notification of this upgrade and beta. **If you have not please contact us to gain access to the beta**.

For the last couple of months we have been implementing additional code and improving existing code. We now have a new version 2.3.4 in beta for clients and selected beta testers only with general release through our website to follow in 2 weeks.

The changes and additions:

- MT4 auto-execution code implemented. Semi-auto mode to follow in the general release – testers should only use demo accounts during this beta
- MT4 auto-detection of lot granularity – user broker interrogated and ArbMaker set to trade to the lot, mini lot or micro lot resolution accordingly
- Negative beta implementation for FX (where it is common) and equities (still under test for the Interactive Brokers execution interface)
- Optimization of data handling code in the MT4 bridge for faster scanning
- Only unit roots test passing at 99% are advanced for cointegration testing. This strengthens the profile of cointegrated pairs coming through the scanner and simplifies the presentation of the cointegration test process as compared to the pre-requisite ‘eligibility’ unit root tests carried out on each time series.
- PACF bypass added to the ‘Bypass filters’ option. This passes autocorrelated pairs when enabled and, for example, permits dual listed equities, such as British American Tobacco (NYSE & LSE) to appear despite the autocorrelation (due in this case largely to the time lag between exchanges). Autocorrelation must not be present for cointegration to be valid; but such pairs can be profitable. This feature a direct request from a client. Note: we do not mark autocorrelated pairs as cointegration fails now but will for the general release
- Dynamic filters now have a master on/off switch
- Pending trades now update in the ‘Open Items’ pane of the ‘Trades’ tab whilst awaiting execution
- Assorted minor fixes and refinements
