Question: What do "A. High" and "A. Low" indicate on MT4/MT5 Market Watch Window?
“A. High” means “Ask High”, it shows the highest ask price for the current day, and “A. Low” is “Ask Low”, it shows the lowest ask price for the current day.
The MT5 trading platform follows the time of GMT+2 or GMT+3(during summer time in US), so the above parameters are shown following the server time, but not your local time.
For your information, there are also parameters for “bid” prices, as “B. High” and “B. Low”.
“Bid High” shows the highest bid price for the current day, and “Bid Low” shows the lowest bid price for the current day.
You can find out more details of each symbol by going to the “Details” tab on “Market Watch” window, but the number of details(data) shown in the window can be limited by your Forex broker.
If the data is not shown, there is basically nothing you can do about it.
