A very important factor that should be influenced is people's mentality. The simulation is free, and the judgment of the transaction is relatively objective, while the real quotation pays real money. After placing an order, people's mentality will change greatly, especially when they first start trading. After opening the position, if the market is slightly unfavorable, you will stop the loss decisively at this time, or subconsciously look for some information that is conducive to holding the position to strengthen your judgment, thinking that the market is only slightly fluctuating, thus missing the best stop loss opportunity. If the market develops in a favorable direction, in the face of profit fluctuations, should we choose to leave the bag for safety or continue to hold it? These are great tests of human nature, which cannot be realized by simulation.

In addition, futures trading follows the principle of price priority and time priority. When a simulated transaction is placed, it will be closed at this point, but in real transactions, there may be many pending orders with the same price, which need to be queued and may not be closed immediately. It has little impact on people who do trend and band trading, but it still has a great impact on people who do high frequency trading.

Whether the simulation is good or not may not be so important, but it still needs to be honed in the real offer.

Of course, a firm trader can also test his strategy by simulation first, which is another matter.
