Hi there, I was looking at tradelink source code recently... it's very nice... I have my own java platform for HFT developed in Java, but the cost of maintaining it become too high. I'm looking to switch to some open source platform. Tradelink looks good to me, but the problem is I would like to be able to extend it by re-using my java code... Is there any comparable platform out there written in Java, so Ii can grow it by re-using my own Java code? Thanks
