Done by GROK in a couple of seconds. It may not be absolutely perfect, but a great place to start.

Question: Grok, can you make an MT4 indicator that will highlight the open, close, high and low of the 6am GMT candle every day?

Here's a clean and efficient MT4 custom indicator that will automatically highlight the **daily 6:00 AM GMT candle** (which is the first full candle after the typical Forex daily rollover).

This indicator draws:
- A rectangle covering the full High-Low range of the 6 AM GMT candle
- Horizontal lines for Open and Close prices
- Labels showing O, H, L, C values
- Works on any timeframe (even M1) and updates automatically each day

### Indicator Name: Daily_6AM_GMT_Candle_Highlighter.mq4

requesting for ur help again please.
I downloaded this indicator from mql5 site.
I think it shows max drawdown based on closed candles. is it possible to make it like plotting info based on tick by tick? the reason I'm asking is because I had trades open with -100$ floating then once they closed all in profit the indicator is showing -65$ as max drawdown. doesnt show the actual drawdown.
also, please have a look if there are any alerts in it and if there are then please kindly remove them.

for some reason I coudnt attach the file itself directly so I had to compress it then it worked.

ps) for some reason getting an error with the attachment will upload once that is fixed.
