The entire trading is based on two very important concepts.....1) Reward/Risk ratio or R/R and 2) Money Management ( MM )or Position sizing. Both these concepts are more important than which of our trade is successful and which is not.
I read a book called " Mathematics of Money Management " by Ralph Vince. This is one of the three finest books on MM by the author and some of the concepts in that book opened my eyes to what trading really is... I am giving below a small excercise from this book to stress a point that in final results, which of your trade made money and which lost money makes NO difference at all.....
THE POSITION SIZING AND MM GAME
Make 40 small pieces of paper,on 20 write SUCCESS and on 20 write "FAIL" and fold them and put them in a glass bowl. Then ask a small child in the family to pick up each slip from the bowl and you read whether success or fail.
The sttarting capital is Rs 1,00,000/- and At each trade you will risk 25 % of the capital. If the trade is success,you make double the amount of money risked on a trade and if it is failure,you loose the amount risked on that trade. So for first trade your cum equity balance is Rs 1,00,000/- and the amount risked is 25000/- so if the slip says success,you make 25000*2 =50,000/- and your cum equity is 1,50,000/- now and on next trade you bet 25 % of 1,50,000/-. so go on like this till 40 trades are over.
The final amount you will have is not dependent on the sequence of your winning/loosing trades,consecutuve looses,wins etc and final amount is over Rs 10,50,000/- Dont believe me ? Try it out. I have spent 3 hrs on this game early in my career and tried coin toss,various sequence of alternate win/loss,10 losses and 10 wins in sequence etc…But the final wealth is same not even a rupee more or rupee less.
What does this prove ? Have a competent system,backtest,have a good mm and trade with confidence. Your sequence of losses and gains make no difference in ultimate results of building your wealth as long as your method has a positive expectancy and edge. Hope you enjoyed the game and learnt something from it…..About expectancy, we will discuss later...
I am no way advocating risking 25% on every trade. This is just illustration because optimal f for this system is 25 %. But 25 % is way tooo high. Start with 1-2 % and put your profits to work for you….
