We have attached an example file setting for a 25K challenge
You only need to adjust Lots, Balance Stop and Balance Target based on your challenge

Preparation
1. With auto trading enabled, start HFT Challenge by loading the right settings file and changing the lot parameter to 0.01
2. Verify that the expert opens the orders after a few seconds
3. If the expert advisor is able to open orders, then disable autotrading and close any open order
4. change the settings to the right lot size and wait for the time of the high-impact news (don't remove the expert advisor from chart)

 

Usage

5. activate autotrading 15 seconds before the news and check the price movements

6. if there are too many losses stop autotrading again and wait for the next news or when the price movement slows down and there are so many losses, stop autotrading

 

Please note that will be more losing trades than profiting trades, but a single trade can generate high profit
