Tomasz,
To select some points from your [interesting] reference:
http://www.interactivebrokers.com/index.html?
html/tws/stop_orders.html~top.body
"A Stop order is not guaranteed a specific execution
price", "exchanges that do not natively execute stop orders", "Buy
Simulated Stop Orders become market orders when ...", "stop orders
will only be elected ...", "for NASDAQ stocks and US Equity Options
which are only triggered after... " etc.
Is this the "all you have to do" and "then go for a walk ". ? With so
many restrictions [and presupposed no web delays] will you consider
your INTRADAY order as DONE ?? And will you call it EOD trading ??
These are some of the dangers when you place delay=0 and you consider
it as EOD trading : the backtesting results will not be that reliable
and may be quite far from the real results.
