The thread was not informative, because as Old Man Morse was trying to point out to jovos, there is no hard-fast rule that can be defined here. It is all up to jovos's broker to define the ultimate rules he/she must follow. OMM mentioned that, and jovos asked again. OMM responded again, and without extra information, jovos will keep spinning his/her wheels looking for an answer on this forum. The direct answer is right in front of him/her now, as I have posted. The answers lay with the broker being used for trading.
OMM has provided a direct answer for what Lightspeed Trading may be able to do for jovos, and it may fit him/her. But if jovos wants to apply what OMM said about Lightspeed's rules to Generic Trading, that may not go well. Every broker is different. It is important for traders to know that, if they have not done due diligence and learned all they can about what they are or are not allowed to do with their broker, then they may get caught unawares in a bad situation.
I did not mean to have this seem like a rant...It is just frustrating that so many people do not take some obvious steps in trying to learn to be better traders...Like, when in doubt, go to the source. If the source and the middle-man do not agree, then get to the bottom of it.
