Very small for every beginner
The market has 6 periods of daily rise
9 AM
12 PM
3 PM
6 PM
9 PM
12 AM
This is Cairo time
So
For example, if you buy any currency at 9 AM, you will find it rising and the price will start to drop until about 11 or 11:30, after that the currency will prepare to rise until 12, sometimes 12:30, after reaching the peak again, it will start to gradually decline to prepare for the rise for the next period, which is at 3 o'clock, and it may increase by half an hour to rise and reach the specified peak
That's why when you find a recommendation before you enter the trade, check the time you are in before you buy to benefit from the profit between each rise and fall
