Since your question notes your desire to see, or check, trend, here's something I use.
Prior to trade, bring up your desired chart, TF not important. Use the spy glass + and - to compact the graph fully. Now, there's you main trend along with your secondary trending. Simple enough and works great.
Overall scale isn't a factor in the MT4. Oh, there are moments when the display will "crunch" on you, especially on vertical scale changes. However, you can find an acceptable medium there.
