Somebody wrote a PM saying:
Sorry if I offended you by asking to see your log. I am a newbie and trying to learn all I can. Some people here on ET, like Niha,
are very willing to help newbies, because they dont see this as an I win, you loose game. I enjoy your posts and learn a lot from them. Won't bother you again.
LOL, you're taking me way too serious, I'm not offended!

Perhaps I should use a smiley next time I reply...
Regarding Niha etc... There is a major difference between the styles in which Niha and I trade. Niha does a lot of trading in "setups" that are recurrent in the way they appear in the market again and again. These setups, while highly effective, are very discretion-and-experience-sensitive, and the more people trade them, the more effective they actually become. So, one could say that by sharing this information, Niha first benefits from selling his information and then he benefits from having more people trade the setup. Niha will likely always get in first, or as one of the first, because he's the most experienced at them, and so the others will follow and reinforce it.
Well, theoretically, anyway. Practically, the ES & NQ are so big that a few people like Niha and followers won't make the hare fat, either. There is massive liquidity on these futures, and that's another reason why it's much "easier" to share information on trading them than on a highly competitive, illiquid contract like DAX, which is what I'm doing.
That's for starters. Now comes the difference between Niha's style and my style; I don't really use "setups" as such much anymore. I use systems based on HH/LL/HL/LH rules, ratios, time pivots, bar excursion and all kinds of things. While definitely executed "discretionarily", these are highly systematic approaches and execution and getting full fills is very critical, particularly with lower liquidity like on DAX. Not to mention my trades are mostly fades, which makes this even way more sensitive again! Even a single trader knowing about it all would definitely make a difference! So, even giving clues to this via things like snapshots would likely be more harm than good. I.e. I have nothing to gain and everything to lose. So?
If you look around ET, you will find that in fact no serious systematic trader or fader will really share intricacies like that.
Mind you though, if look around for traders that trade setups like Niha, or traders that just trade purely off-feel like Mark (velocity_trader), they will always be very helpful and willing to share on their respective field, not least since it's in their own best interest to add liquidity via doing so.
That said though, I have shared $h*t-loads of stuff on this forum, anyway, and if you dig a bit, you'll see I've said a lot more than I should have many a time.
I hope this clarifies things for others, too.
Warmest Regards,
Scientist.
