A trader is someone who buys and sells.
So is the financial market except for some difference. List below are some guide to help before taking a trade.
Firstly before you open a position, make sure that you analyzed the chart. Starting with weekly time frame. You should identify a market structure and spot major key levels.
Secondly once the chart is analyzed, you should identify the safest trading areas for your strategy especially support and resistance (supply and demand). Don't just jump into any trade. Buy/Sell stop or buy/sell limit can be very handy.
Thirdly you must set a stop loss and take profit. Remember that your stop-loss defines the point where you become wrong in your predictions while your take profit is the level you expect price to reach. Take profit is very important as price cannot continue that way for long don't let your greed and fear intervene.
.Be very careful on that step and give the market some space for fluctuations.
Though there are market makers, and sometimes there is manipulation. However, following the steps listed above will help you alot.
Remember that the market does not belong to anyone.
Try joining some forums too or telegram channel that will help.
