Here's some good rules.
1) If you are feeling any emotion during a trade, don't take it and/or kill it. Also, before each trade mentally prepare yourself that it can and will be a loss, if you are not ready to accept a loss at that time, don't initiate the trade.
2) Set a daily loss amount for the day for example say $ 500. If you are around that amount, stop trading.
3) If price is headed for your stop, don't move it, hoping that price will not reach it if you move it. Hope is not a trading plan.
4) Set a time for when you want to trade based on statistical evidence, and show up at that time. If it's hours before or after, just don't trade that day or night and wait for the next one.
5) Create a trading plan.
6) Follow that trading plan.
7) Especially when you start, create a spreadsheet of your trades and reasons why each one worked or did not work.
8) Don't take trades based on postings of trades here since your risk vs reward can be vastly different.
9) It can take 10 years and/or 10,000 hours of screen time to become consistent.
10) Understand margin. On Futures and Forex, you have extreme margin which helps you use less money trading, but if you do too many contracts per trade you can easily take a big loss on just a single trade. Also, remember in volatile markets you should cut back the number of contracts per trade and instead look for expanded targets and stops.
