I didn't delete this post, but I deleted the one that you started promoting SL4 in the software forum. I also deleted another thread by a different user promoting this firm. This site is paid for by sponsors, so it's inappropriate to create posts which are blatant advertisements. It's ok to discuss your software with members here, but if a post looks like a spam it will be deleted.
As regards the software, I am doing a demo this week. I can't yet speak as to the effectiveness of the signals yet; if I have some time over the next couple trading days I will try to evaluate how well the signals work. It's not an easy task, and probably takes more than a one week demo to evaluate, since there are other indicators which confirm the signals themselves. I have to say I'm impressed with the level of sophistication in the system, and the work I'm sure the developers put into the software. Whether that translates into profitable trades, that's another story.
A couple things concern me. I was comparing level 2 quotes against IB and Redi Plus, and SL4 was consistently a couple seconds behind. I did some simulated trades, and ISLD would take about 5 seconds to execute when there was liquidity present the entire time.
Also, I'm not 100% sure on this but it appears that there are certain securities that aren't 'in the system' and can't be traded. I tried to do simulated trades on these, but they never went through. So if you trade some less liquid stocks, they might not even be available for trading. I'll check on this to make sure.
