I would like to give a tip to everyone who is starting out in the market and intends to carry out short or very short-term operations. Divide your purchases into 4 parts; how? Draw 4 support lines below the price at which the currency you want to buy is trading and follow them strictly as buying points. Many times you will not even reach the third purchase and already make good profits. After drawing the 4 support lines, place two resistance lines above the current point (or at the current point if you notice that it is at a resistance) and follow both lines as selling points, without concessions and desperate sales; the first line being the safest and most accurate that the currency will reach again and the second if you are willing to take more risks and wait a longer time to sell.
This method is very effective because it provides security in times of decline, such as those seen yesterday and today, because even if the currency continues to fall, you still have funds to buy and can wait for the market's pessimism to end more calmly, bringing your exit point without losses ever lower and consequently the profit point can also be reallocated to one of the previous support lines that will now possibly serve as resistance (although I recommend waiting until the resistance lines initially drawn, which will give an exceptional profit when reached).
