When I started trading as a novice, it was very hard to understand that every trade profit I saved will ultimately was a loss to my Investment.
Then I realised that there were some deductions with every trade. So I started analysing through hard way as to why did it happen. I also lost lot of money initially.
My pnl will show profit but at the end my total was decreasing.
Here are some hards facts you need to understand.
1. Binance charges fee for every trade. You order a coin, you cancel a trade, you order rebuy, or you make change to your order the binance will charge you.
So when you earn 10 dollars through 3-4 trades, 3-4 changed orders, 3-4 cancelled orders or 3-4 new orders, you got to pay for all these and at the end you pay a fee of $12 against an earning of 10. You can check it yourself.
How to avoid it?
Strategise when to buy whether at cross lines or when it is rock bottom its your choice. I prefer rock bottom time.
Buy a small amount say if you have a total of 1000, start with 20 or 30. Now wait and see the swing. if it goes down wait more. if it is going up be quick but purchases should be in 8-10 trades.
Now keep the selling open if you have time to monitor the trade or price. keep watching and let it go to the optimum top as per your desire and of course the trend. And then when you see you have some dollars in your cuff sell it in 1 stroke.
if you can't monitor then you may put a limit sell but I prefer monitoring.
This way you are using 1 trade and paying 1 fee only.
Keep the Selling Order Open, no changes in between. This will save you lot of money.
Good Luck
