The best days to run the Traide Ringer in the forex market are Sunday at 8 PM EST thru Wednesday 2 PM EST. Exceptions would include known financial events that would cause potential volatility and the NFP week.
Thursday and Friday are the biggest drawdown days and should be avoided.
We understand that there are times when a person may already be in drawdown on Wednesday and instead of taking the loss the person will trade into Thursday and perhaps even into Friday. This does carry with it risk and there are times when it works and other times when the loss becomes greater and taking the loss Wednesday night would have been the better option.
Learning how to predict where the market is going on the trades that you are in is valuable knowledge and effort should be put into understanding this process as much as possible.
One good way is to look for your currency pair on TradingView and seeing what the market sentiment is and if it could go in your favor.
Here is an example of EURUSD and if you were in a buy trade and saw this you may consider taking the loss as the market sentiment is to sell. This is just a tool and does not tell you what the market will do since the market can be unpredictable.
