Hi everybody,
Question in the title is maybe silly for many of you. But think about it...
1. If you have no system, no trading plan, your result ( excluding commissions ) depends only on your luck.
2. If you have a system or a plan, your result depends on certain future market behaviour ( level of volatility, # of gaps, etc. ). In general, trading systems can only follow the trend or play against the trend. If trends will rarely change, systems that follows the trend will win. If trends will often change, system that trades against the trend will win. You can't predict how long trends will exsist, when they will reverse.
3. Same applies to life. Can your decisions bring you more success? Your life decisions will bring success only if things/events/situations are "on your side". If you don't have luck, you'll not succeed. Think about approx 4,5 bilion people in this world who's living standards are very poor. When we are born, we are all the same, or we differ due to genetic or other issues that are beyond our control. Than life goes on, some people have a great life, some not. Is it because people have completly different level of skills, intelligence? I don't think so.
4. How to check is your trading result was made by pure luck, or does your skills create good result?
Let's say, everything depends on luck. So, the expected value of your result is zero. What's the probability that your trading results can only be explained by luck or bad luck?
I think I know how to check this. I give an example.
Let's say your trading statistics are:
Average profit: 8
Average loss: 4
Number of trades: 100
% of profitable trades: 50%
Total P/L : 200
On average you should have total P/L =zero. With av.proft/av. loss ratio =2, % of profitable trades should be 33.33.
But you make 50%.
What's the probability of 50% or more successes in 100 shots, with a 33.33% chance of a single success? Answer: only 0.02%
So, if you have a system that have 50% profitable trades, with av win/loss ratio 2, and 100 trades, probability that it's result was created by luck is only 0.02%.
If someone of you has a trading system like that, I would have to say, that not everything depends on luck and trading skills are important.
