Online trading systems enable banks and financial institutions to automate the buying and selling of financial instruments with their corporate and institutional clients. Automation reduces the bank's internal costs and improves service to clients by offering 24x7 trading, a faster response and a broader range of financial products.

Banks aim to offer online trading of all asset classes including: Cash, Commercial Paper, Bank Bills, Discounted Securities, Repos, Fixed Income and Foreign Exchange. There are significant cost advantages if the same system can be used for all asset classes. In addition, banks seek to offer Exotic, Cross-instrument products to their customers. This requires a unified infrastructure across products. PTX supports all asset classes on the same infrastructure, making the online trading initiative cheaper and allowing Exotics to be traded.

PTX is also exceptionally flexible in enabling Regional/Correspondent Banks and financial institutions create electronic trading support for new instruments on the fly without having to modify the application’s underlying architecture.

PTX also supports creating products of existing instruments specifically suited to be used by other financial institutions such as flexible credit facilities, guarantees etc. Instruments in PTX can be easily created by simply defining instrument attributes such as face value, interest rate, base rate, deal rate etc. Products (subsets of existing instruments) can similarly be easily created by defining product attributes such as EFP Eligible, Coupon frequency, ISIN, CUSIP etc. in the case of Fixed Income products.
