Odaily Planet Daily News: Trader Eugene Ng Ah Sio has released a recent SOL trading summary, stating that after perfectly long BTC from $102000 to $107000, he has decided to transfer this profit to long positions in SOL and the SOL ecosystem. At that time, the entry point provided a moderate risk return ratio (r/r), specifically: a long position of $220 for SOL, $2.75 for WIF, and $0.037 for BONK. This is based on SOL's strong performance in low time frames (LTF) and the confidence brought by the success of previous transactions. When the BTC market began to turn around at 108k, they didn't like the trading performance of some meme coins, so they decisively liquidated the underperforming assets and accepted an acceptable loss (which was the right move). However, it did not liquidate SOL's position, but instead chose to increase its position from $20 million to $30 million. This led to the formation of the first error. Mistake one is not timely stop loss: It is usually advisable to exit in a timely manner when the position begins to lose its strength, in order to avoid greater losses. However, this time we chose not to cut losses when SOL fell to $215. Although we believed that the market would experience downward volatility before and after the FOMC interest rate meeting, bias overwhelmed logic. $200 is a key support level for SOL, and it is very close. We do not want to be "cut off" by the market for trying to seize the 5% volatility. When SOL fell to the support level of $200, it further increased its position from $30 million to $45 million, citing the best risk return ratio at the high time frame (HTF) support level. The second mistake was ignoring the stop loss point: when SOL fell below $200, the clear action should have been to close the position according to the plan. However, choosing to continue holding because the position size is already so large that closing it at this time could trigger a waterfall drop in SOL prices to $190 and disrupt the entire chart. At this point, one begins to hold onto "hopium" and think that "there may be a downward trend that falls below the support line and then rises again". This psychological state is definitely a red warning signal. In addition, when the price fell below $200, leverage was added in the range of $187 to $193, expanding the position size to nearly $60 million (total account leverage reached 1.2 times), which was clearly a wrong operation and the errors began to accumulate. Fortunately, there was no complete 'black swan' event and no greater punishment was imposed as a result.
