MT4 is old-fashioned, like a hammer always ready. It launches fast, handles charts with ease, and gets trades going with little fuss. That simplicity hides dangers, though. Go slowly, learn the peculiarities, and you'll be alright.

Choose a broker with accurate quotes and a low cost at peak hours. fxcm client first trader driven
Look at the ping in the bottom right corner; if it's green, you're good. Try it out on a trial setup, and then migrate to a small live account. Pay attention to slippage when markets open and during events. Trade small positions until the platform feels like muscle memory.
Set up charts once, keep them as layouts, and use them again. Profiles help separate setups. I like to have one profile for each session: Asia, Europe, and US. Use simple tools. A moving average or two, RSI, and volume can get the job done. There are too many toys on the screen.
Shortcuts cut down on clicks. Pressing F9 brings up the order window. One-click trading makes exits faster. Use Ctrl+Y to toggle session breaks to see how the session behaves. To measure pips, use the crosshair (middle mouse button or Ctrl+F). A quick drag gives you scale and price moves. Useful when rushing decisions.
EAs are automation and edge. Use Magic Numbers to separate trades. For better modeling, try "Every tick" in Strategy Tester, but trust forward tests more. A VPS close to your broker's server cuts down on latency. Keep logs; the Journal shows what happened if an EA goes crazy.
The kinds of orders matter. Market orders trade at once. Stops push prices further. Limits catch dips. To avoid mistakes, put in stop-loss and take-profit when you enter the position. Partial closure splits the trade to manage risk. Trailing stops operate on your PC, not the server. So, either don’t shut it down or utilize a VPS.
Think about the rules of the broker. Some let you hedge, but others block it. FIFO is how US accounts work. Five-digit brokers use points instead of pips. One pip is generally equal to ten points. Error 130 says "invalid stops" rather loudly. Make the stop wider than the current price. "Off quotes" is what Error 136 signifies. A problem with liquidity or connection. Try again or make it smaller.
Make sure your work area is organized. Use Ctrl+B to remove clutter. You can change or delete indicators by right-clicking on them. Load "Default" and rebuild if a template stops working. Make a copy of the folders for MQL4, templates, and profiles. Having a copy stored makes a crash less alarming.
Keep access safe. For read-only sharing, use the investor password. Never use someone else's EA on a live account. Check the code for trading functions and strange web queries. Your setup can be one-of-a-kind without being risky.
Watch out for swaps, commissions, and server time. Highlight events on the chart. Be very careful while trading during news spikes. Make sure the size of your position suits your plan by double-checking it. Small edges, applied consistently, beat one-shot bets. And if your hand shakes, back off. After coffee, the chart will still be there.
