Opening and closing points of both Bullish and Bearish candleKnow what is Bullish and Bearish candleHow to use a 4-hour time frameThe market trend, whether the market is on an uptrend or downtrend zone
This is the simplest strategy that is beginner-friendly and anyone can use it to make a profit in the features market.
Here are some things you will need to check before entering the market for a profitable trade,
15-minute time frame30-minute time frame4 hours time frameThe closing point of the last candle is in the 4-hour time frame and the opening zone of the next candle is in the 4-hour time frame.The market movement in the first 15 minutes.
Follow the procedure below for a successful trade entry and exit while using this strategy
Chose the coin of your choice that you would want to tradeKeep your eyes on the 4-hour time frame, make sure you are there when a candle is about to close and open for another 4 hours.Check on the candle closing point or level, and wait for the next candle to begin, give it a close look for the first 15 minutes and check the direction of the market to see if it is going up or down. Enter the market for the first 15 minutes after knowing the market direction, please listen and read the next sentence which is so important.Before entering the market within these first 15 minutes, please make sure that you have already checked wether the candle (market) movement is up or down to know wether you are taking a buy or a sell trade.This is how you will know when to enter the market, 
First, when you use 4 hours as your trading time frame, always watch the first 15 minutes to help you enter the market at the right time because when the candle opens after the previous candle is closed, it will first go down or up. So when it goes up for the first 15 minutes please take a sell (short) trade because the candle will turn direction immediately after the first 15 minutes.When the candle goes down within the first 15 minutes take a buy(long) trade for a good buy opportunity.Remember you will make all these trades or choices after knowing the market trend.
  Please only use this method with 4 hours candle and that is why I call it trading within a candle. 

For a good market exit while using this strategy, this is where the 30-minute time frame comes in, for a good exit make sure you check your 4-hour candle to see how many minutes remain for the next candle to be formed or opened.

 Always check on your watch to make sure that you exit the market in the first 2 hours of 4 hours time candle to see the next candle movement in the next 2 hours for another trade opportunity, this is because sometimes the candle or market can change direction that will help you know the next candle movement if you are keen enough.

If you like you can enter two trades within 4 hours for more profit while using this method if you are wise enough. Please remember to be keen and checking on your trade to avoid missing the exit or entry zones, set take profit get in or out of the market depending on your target, please avoid being greedy.When you decide to take another trade, make sure you exit the market within the second last 15 minutes because, within the last 15 minutes, the candle will be preparing for closing to get time for the next candle opening,
