I am planning to go to mumbai. All traders willing to get together to design a vehicle that is powered by a motor, and should seat 4 to 7 persons please quote this post, and I shall post the job on freelancers, and we can then get a low cost vehicle to travel anywhere, for life.
Why re create and re invent the wheel, when what a dedicated trader should be doing is concentrating on trading.
A minuite spent on some other task, is a minute that could be spent to refining your trading system and execution.
1100 odd rs is charged y neotrader per month for official data and some 1300 odd is charged by GFDL, that is just a part of ypur business expense, morever, it can be ofsett in your taxes as business cost.
So, where is the need to develop software?
Now the argument could be, what about small traders who need to keep costs down, to survive the 2 to 3 year learning period?
Fact is, without accurate official data you wont survive that period, and will go back to your job or shop, or other business.
So, if you are here to make a living, go for official data. Period.
Yes, what you can do is buy collectively, and negotiate with the 2 companies mentioned above. That is sensible.
By the way, once we design the motor powered vehicle, we will all get together and post a job on freelancers to develop fuel for us, so we can just make our own fuel too.
