Maybe I should clarify.
If your real time trading requires indicators to be updated only
at the close of each bar, then WL will work fine. I know of
some realtime strategies that make a decision based on the last
few closed bars and then place limit or stop orders that will be
executed later. That should work fine with WL, provided stop and
limit orders are accounted for intra-bar when they're hit.
Other strategies require place stop orders or limit orders based
on an indicator value, not on price. Say, if a 13-bar RSI touches
88.5% then execute an order immediately. You can't wait until a bar
closes because then it would be too late. You need the indicator
updated in real time, tick by tick. WealthLab cannot do this.
TradeStation can. NEITHER program can be programmed to trade such
a system mechanically (because strategies don't update every tick,
only indicators), but at least with TS you can watch the indicator
with your finger on the order trigger. I know one mind bogglingly
successful trader who trades this way.
