1, the most important thing to remind is that using VPS is not absolutely safe, there will be some risks, but it is relatively safe.

2. A VPS can only operate an Amazon account with one identity, but a computer can log in to multiple VPS, which is equivalent to a computer operating multiple accounts.

3. If an Amazon account has been blocked on the same computer and the same line, you can also apply for a new account through VPS, which will not be associated. However, it is necessary to ensure that a clean VPS is used to apply for a new account.

4. Some sellers report that it will be very difficult to use VPS. In fact, you can freely choose the configuration when purchasing VPS, so it will not be slow to choose a higher configuration. As for what kind of configuration is not stuck, you can refer to the following configuration: cpu single core, memory 2G, bandwidth 1m, which is more cost-effective.

5. After purchasing VPS, the link can be successful only after VPS is turned on. Of course, if it is opened or the link is not available, you can only go to the customer service staff of the buyer to solve it.

6. After using VPS, if the account is blocked, the used VPS can no longer register or operate the account with other identities. If you want to register a new Amazon account, you need to replace it with a new clean VPS. Of course, computers and network cables don't need to be replaced.

7, multi-account operation, you can also use 3G network card. 3G network card with computer, network cable with computer is the most conservative and safest method.

8. Let me say one more thing about multi-account operation. If you operate multiple accounts, it is suggested that each account has a different trademark and operates different types of products. The reason is that if the product categories are the same, keyword advertisements will be repeatedly placed in the later period, which will waste traffic and account numbers will compete for traffic, which is very unfavorable for creating explosions and accumulating favorable comments. It is easy to doubt this connection.

Can vps browse the web?

The vice president can browse the web. Only in the domestic environment, the access speed will be slower.

As long as the IP or port is not intercepted, all public IPS can be interconnected. If you still can't log in, the login is stuck or slow because of configuration reasons.

Vps refers to virtual private server, which is a network technology that allows multiple host names to run on a server (or a server group), and can support each host independently. The simple understanding is that VPS is a system isolated by virtualization technology.

Ladies and gentlemen, how to import prawn tick data into mt4?

If it is the back test of MT4, several points should be noted:

1. If your strategy is based on tick data, backtesting must achieve at least 99% accuracy. (For example, using TickStory to download data and backtest)

2. If your strategy is sensitive to price difference, it is recommended to use auxiliary tools to carry out data backtesting of real floating price difference instead of MT4' s own fixed price difference. (for example, using TickDataSuite)

3. If your strategy is sensitive to slippage, or if you place an order at the moment when the market breaks through, or if you use a stop-loss order, you must use a slippage generation tool for backtesting (such as TickDataSuite), or convert the code to another platform for backtesting (such as JForex), because the default backtesting of MT4 will not have slippage.

4. If your strategy is time-sensitive, please pay attention to whether your backtesting data is set in the correct time zone.

5. If your strategy is to close the position with a stop loss, it should be noted that the backtesters of MT4 will ignore the real price and close the position with the SL you set, which will lead to a great difference between the results and the real quotation (for example, for multiple orders, SL is 1.00 150, and the previous closing point is1.00/kloc-). The next ticking point drops instantly 1.006666 My solution is to use JForex backtesting (JForex's SL is consistent with the real quotation, and supports EA conversion of MQL4, which can basically succeed without using any unpopular code).

6. When there is no problem with MT4 backtesting, it is suggested to backtest the same strategy on JForex and cTrader in the same time period. If the backtesting of the three platforms can ensure profitability, then the company's profits will be very close.

7. If your strategy depends on the order placing speed, you should pay attention to the delay between your VPS and the broker's server, and the actual execution speed of the server's order, both of which are indispensable. I once tested a strategy. The server delay of VPS and Broker is 0.5ms~ 1.2ms, which meets the demand. However, I found that the order execution was very slow. After testing, I found that the average processing speed of each order needs to be 200ms~400ms, and there is an ultra-slow speed of 1500ms from time to time, which makes the firm offer unprofitable. Finally, I changed my agent to solve it.

8. When the above points are all right, if you prepare a firm offer, it is recommended to use the lowest position (such as 0.0 1) to test for at least 3 months. If it is consistent with the expected results, it can be carried out as planned.

Think so much for the time being, greenpipstoyou!

How much server space does an enterprise website generally need?

Generally speaking, the company's emphasis on the website and the company's strength will also affect the choice of website space.

General enterprises can choose to buy the service provider's space and store the website's programs by means of regular renewal. However, companies with relatively strong strength can also purchase VP or directly configure their own servers to achieve absolute control over the website space.

Just use a 500M one for the enterprise station. If the website data is relatively large, you can consider changing vps or cloud host, and you can use space in the early stage. The size of the website space is actually the size of the server hard disk that the website can use. Common website spaces are divided into 100M, 200M, 300M, 500M and1g. So, how much website space does an ordinary website need? We need to calculate this, taking corporate websites as an example. If the size of the website program is10m; The website database is generally 50M, and the pictures and video files of the website occupy most of the space of the website.

If you have 1000 products to publish on the website. Generally, the number of pictures used on a web page should not exceed 200K (the larger the picture, the slower the user will open the website).

In this way, this 1000 product takes up about 200M of space at most, and all the space adds up to about 260m, so we think that 300M is enough for a general small business website.

Of course, some special industries are not necessarily the same. For example, customers who have a large number of pictures, such as photography, need more space because of their high quality and large space. The same is true for industries such as video and audio. In short, we should make an estimate according to the actual situation.
