For support and resistance I usually start by marking the obvious swing highs and lows on the higher timeframes like daily or 4h since those levels tend to hold more weight. I also look for areas where price has reacted multiple times because those zones often act as strong barriers again. With Fibonacci, I anchor it from a clear swing low to swing high (or the reverse in a downtrend) and then focus on levels like 38.2, 50, and 61.8 which often line up with structure. On Valetax I use MT5 for this since it makes drawing and adjusting zones and fibs pretty straightforward, and sometimes I cross-check with Analysis IQ to see if fundamentals line up with the technical levels.
