openquant, wealth-lab, tradestation, etc really depends on your frequency. for minute to second level trading, I found no commercial package really works.
This is the only way. You are borrowing money from yourself. It doesn't matter whether you are paying interest or not. This loan doesn't affect your ability to pay other loan because it is your money. It doesn't show up on your credit report either.

for these level, backtesting won't work. Because you really have to consider slippage, market impact now. I don't see how that happen with any simulator. I mean even IB automatic trading paper account is debatable. The whole mechanism is still black-box. You don't know under what condition, your MKT/LMT order will be filled by your paper account. And I don't think it's reasonable to make any assumption.

depends what you trade, I guess 2-5 minute will still be relatively ok for top liquid stuff.

it's still not bad if it's just opportunity cost, like I mentioned before, you could be stopped nowhere if you use stp, and failed to fill if you use stplmt. not sure, if one of the solution would be stplmt but keeps reducing(for long) lmt if price gap down beyond the limit. so, to backtest one minute level strategies, one really needs tick data, one minute bar won't be sufficient.
for stop, I think you need to use your own mechanism to stop. the one you submit to the broker earlier is visible to others and could be used to trigger.. my stop algorithm is quite complicated and always do much better job than myself.

stop limit orders are probably candies for market maker. I felt the same way, but haven't think it through. I think your are probably right in most case, in a relative low volatile market, stop by your own instead of submit a child stop loss order is most likely better. But for high volatile market, it's a trade-off, depends on how fast your program is.

yeah.. bad opportunity is easier to fill.. market is always right.. after watch the movie of "source code", whenever I get good stuff not filled when I was in the queue, I will just think that in another m universe, this order is filled. and that village head is happily counting money already.

that's a good point, as I felt I was taken advantage of by market maker more frequent than I thought. Regarding ES, the spread is 99.5% one tick. I really don't know how market makers profit unless majority orders are from market makers.

tradestation is pretty good already. if there is some probability involved, you may not see the same result every time.
