The essence of trading is: cut losses when wrong, hold on when right, small losses and big profits, manage substantial gains and losses. Specifically for each core step:

1. Trend Following: Find a simple moving average to distinguish between long and short positions; only go long above it, only go short below it.

2. Testing Position: Go with the trend, follow the major trend while countering the minor trend; when entering, consider a potential large risk-reward ratio. Entering at this position means if wrong, the loss is small, but if right, the profit is substantial, typically at the trend bottom or early stage of the trend.

3. Testing Position Stop Loss: If a key point is breached, you must stop loss; no room for luck. If the price comes back, look for another opportunity to enter. Avoid having a mindset of relying on luck, thinking that it might rebound; also avoid averaging down losses.

4. Trend Position Stop Loss: For newly added trend positions, move the stop loss to the new key point. The base position is already safe, leaving only the stop loss risk for added positions. If it fails, stop loss for the added position and wait for the next opportunity. If it continues to rise, hold firmly and wait for a pullback to add positions, continuing to move the stop loss. Until the last move is stopped out or a head signal for profit-taking appears.

5. Profit Taking: Never easily take profits at any time; this is the key to making big money. If it's a right-side trade, unrealized gains will definitely pull back; you must accept this mentally. Don't think about selling at the highest point, or after selling, don't dwell on the fact that you didn't sell at the highest point. Selling at the peak requires both skill and luck.

As long as you can understand and adhere to these principles in practice, maintaining consistent discipline, you will find that making money is a natural outcome.
