Is Instaforex the Right Broker for Scalpers?

@ milka amelia:

For scalping, you can choose a broker that offers the lowest possible spread and the highest possible leverage. Whether InstaForex is included, please read: Best Brokers For Scalping

You can also compare the spread and leverage of each broker.

Is a good scalper using 1 Minute TF or 5 Minute TF?

@ Kusmanan:

Use a time frame between 5 minutes or 15 minutes.
Avoid using a 1 minute time frame because of a lot of noise or errors in price movements. Noise will affect the reading of price action and technical indicators, which can result in incorrect signals.
