Can I take from that statement then at least it is possible with some hard work to actually do this.
Absolutely, just a lot harder than you imagine at the moment.
What's the difference between making a killing on demo platforms and doing it in real life, is it simply that having a smaller trading account limits you more (obviously I guess) or is it a more psychological thing - that even with a £20K real account it would not be possible to replicate the killing you made on a £20K paper account?
The psychological thing is the biggest barrier here, ill give you a example below of a demo trade i made that opened my eyes.
I made this demo trade over a year ago, to cut a long story short, I wanted to jump on the bandwagon of the facebook ipo due to all the hype that surrounded it, i had been very successful on many other trades over previous months trading from gut feeling with no strategy, so i saw this as a big earner.
My thought process was that:- facebook chose nasdaq to float on, I checked nasdaq on the daily and h4 charts and found it was in a noticeable uptrend, So, with one of the biggest ipo's going live at a certain time of day this baby is going to sky rocket. I went long on the nasdaq about 50-100 £/point, not sure which.
I often felt smug that i was choosing all these winners and making all this money with virtually no experience, a natural one might say, ha ha .
Anyway, price began to steadily fall leading up to the open time, I wasn't worried though because it was going to spike through the top of the screen very soon, I held in as it continued to drop, the open was delayed for whatever reason and price was still falling, I am about 3k down now with no stoploss, no money management and no strategy, destined to fail. As the ipo went live it tanked like a brick, so did the nasdaq.
So now im down about 7k, It then becomes damage limitation, I kept saying to myself once it rises back to "x level" im out, Price would come within a few points of this level then drop even further. I eventually closed out about minus 9k. The whole trade was wrong from the open, did it bother me ? No!, because its only demo cash, did i learn from it ? Absolutely.
