>> You could use a combination of backoff and payup ticks.
@patrickrooney , I have in fact used payup ticks while using TT. I know this may not be the fault of the paid up ticks but when I attempted to close the trade, it reversed my positions. TT support came in and attempted a fix - remove the quote on 1 leg instead of 2. My spreads since then closed properly but after a while the problem returned. Out of frustration, I changed to T4. Maybe TT has fixed the issue, we don't really know until I go back using TT.
Now with T4, everytime I put a spreads trade, the bid ask spread seems to be a lot wider than a trade done in TT. One could debate that volatility, timing could have played a part, but as a person who keeps seeing this; it's down to either I am not setting up my spreads correctly, or that TT has some advantage over T4 - yet to verified this.
I cannot help but feel that building an autospreader on my own could be a better option. The interesting thing is I want to earn a profit and not waste time troubleshooting autospreader issues. See the catch 22. If you need to build one, you will need to spend time troubleshooting. Until I trade bigger accounts would building your own autospreader be the way to go - lower cost and to resolve problems and not deal with software companies making changes creating new problems.
