1) If you invest the same time/effort you spend learning trading into developing a skill or starting a business, you'd probably make more money.
I know some of you may not agree, but this is true for me especially.
2) The way you set your life up has a lot of impact on your trading
It is true that psychology matters a lot in trading, but i always realise that the way you set your life up impacts your psychology while trading the most. If your life is chaotic, unordered, those emotions will come back and hurt you when you are trading. You will simply not be in the right state of mind to make decisions regarding your money. If you have psychopathic girlfriend or unstable/abusive relationships, you need choose in between that or your trading career, but not both.
3) The market is ruthless.
Trading is a zero sum game, actually, its a negative sum game, since the house gets their commission. In order to become successful, you have to be cold and calculative. You have to assume that the world is out there to get you. The market is ruthless, its filled with people who wants to take your money, this is no place for nice guys!. Whoever is on the other side of the trade, he wants to take your money , so dont feel bad when you take his.
4) Your strategy has to match your personality.
Many years ago i used to have this football strategy that involves backing unders if their league average goals , pre match stats and in play odds meet a certain threshold. The strategy works fine but it always blow up in the end. The reason is because i become anxious whenever i back unders. I would watch the game and shit myself everytime there is a shot. My heart ends up in my mouth when the teams attack. In the end it ruined my mental state and when the inevitable goal goes in i would become angry and double down to recoup the losses... and sods law determine that there will be a few more goals and i blew my whole bank. I never develop any strategy involving backing unders anymore. All my current strategies are betting for goals and i never blew my bank up again since you only lose when the game ends and when the game ends I cannot double down anymore. I do feel bored when there are no goals but better bored than nervous/angry.
5) Trading is 80% crunching data, 20% actually trading.
Trading is actually for the most part collecting, cleaning and crunching data. You goal should always always always be looking for mispriced market. Your edge should be the willingness to look deeper into the numbers. Say for example, just because one striker scores more goals than the other for the same game time doesnt mean he is a better goal scorer. He might just have more chances than the other. You need to be willing to dig deeper than other market participants, create your own rating system and then find if there are any mismatch in prices. The football market is fairly efficient, but its not impossible to find value. If you manage to find value, a straight bet is actually pretty sufficient.
Learning a programming language would help you greatly automate some of the tedious process. Python and SQL would be a good fit, and Excel too, tho not a programming language.
6) Trading should be for capital appreciation, not for income.
I never understood how people can trade for income. If you trade for income, you will have to take out money from your bank for food and bills and stuff every month. Then you will never be able to compound your winnings and grow your bank. Not to mention if you feel the need to make a profit because your livelihood depends on it, you might "force a trade" even when the circumstances does not provide one.
7) A lot of opportunities dont exists in the top flight football
The top division of each country's football league are always the most liquid, but also the most over analyzed divisions. its going to be more difficult to find value in those leagues. Opportunities exist more often in lower leagues or more obscure leagues such as championship , ligue 2, series B, Singapore, Japanese, Polish leagues due to the smaller amount of attention they get. Yes it also mean that those leagues are less liquid, its a trade off you have to accept. I forgot when was the last time i traded the premier league. Its too well priced because information for those in top flight football are too abundant. If you wish to find opportunities, look away from top flight football.
That's all. Thanks for reading
