Hi @polat06, I have replied yours.
It’s not advisable if you are not familiar with the concept. Make sure, you are careful to try such thing to good broker. Hardly can find a replacement. If the broker is not so good, blacklisted you, it’s easier to find a replacement. Blacklisted from a top tier broker, will be a big no no for your trading future. 
Before I discuss more, you have to read through the ToS from a brokers. Bellow is ICMarkets.
As you can see, HFT is one of the techniques has risk to be suspended.
I won’t say I do HFT on ICMarkets. ICMarkets is one of the best brokers. I won’t do something funny and got suspended. I will try to obey their rule as much as I can. 
The key to do HFT, most likely something to do with Arbitrage, News Trading, Low Market Volatility and few others.
The most robust HFT comes from arbitrage. It’s known as the devilish art of making money. But it’s also the easiest method to get caught.
If you know the way to do it, obviously, you can’t share to others. Reason, when a broker know how you do it, they will patch their system then, you no longer able to earn money from the hole.
When you know the hole, you need to use it wisely. Don’t be too greedy, or it will get noticeable and no longer available.
I will share you my past method, so you can imagine how to do it. I wont tell you frankly the method I’m using now. I don’t know if there is broker here. Or you are also owning a broker 
. If so, I will lost my money engine.
Around 2020, it was an era of arbitrage party in cryptocurrency. Cryptocurrency Centralize Exchange (CEX) were not connected well, so there were many tokens were sold with different prices. Example CEX A sold DOGE from 1.5 USD, CEX B sold 1 USD.
By having the different, we can create a script to monitor price from different exchange. I used python at that time. Monitor few CEX looked for the cheapest asking price, bought them as much as I could and sold them to the highest bidder.
If I monitor 5 CEX, 1 CEX need 1k USD to operate, I will need 5k, 1k for each CEX.
The procedure will be done this way:
This is the simple HFT was done in crypto during 2020. You can do this after you know all the cost, latency, window opportunity available. Now this method hardly can be done, since all CEX will do arbitrage to each other, it makes market becomes more efficient.
Can we do this in CFD? Yes of course to some degree and a little improvisation. You need to monitor the price movement, look for spread. Look for the weaknesses. You need to create a script to compare price and find out when the weak spot appear, and how to make use of it.
It’s not an easy way. I need years to find out the spot. When the spot disappear, I have to find other method again. So, the method always changes. You need to know how to code and analyze market properly. 
@TYGMedia I am not a broker , I am just a simple person trying to learn ,you can give me your method with ic markets in private, I will never share with any person , I am waiting all these 6 years searching to find someone who can help me to do arbitrage or HFT , I send you message brother.
Hi @virtu0s0, I won’t talk here since it is against broker’s policy.
The clues are: It’s sensitive to particular server, trading time and news. You have to monitor they price movement closely. If you are a programmer at least MQL4/5, you should know how to monitor it. Get the data, write to file, analyze the data thoroughly.
The weaknesses keeps moving, so you need to have skill to catch it for profit. If you don’t know, it’s better to stay away.
Hello sir, I need advice from your experience in the field of HFT trading. I have a robot that trades on the index US100 US30 and several other pairs and does not use the arbitrage strategy, but it wins in the demo account and loses in the real account. Even if I run both accounts, the demo and the real, the entry price for deals is different. I spoke to IC Market support and their response was that I need a VPS. I tried a VPS with 8 cores and 32 RAM, but the problem was not solved. Please, if you have a solution, direct me to what I can do.
Hi @majid46, I don’t know your HFT’s method. It’s difficult for me to give any advice.
HFT needs market imperfection / anomaly. Using demo account, there is no imperfection. So you can never test HFT on demo account.
You need good VPS to run HFT. It also need good connection to broker’s server. For example IC Markets’ server at New York, so VPS near NY will be the best.
You probably depend on slippage on demo server. In real market, slippage is different.
Developing a good HFT bot will need great sacrifice. You have to use real account instead of demo account. The same reason no body want to disclose their HFT secret.
@majid46 Use ultrafx vps , their ping is less than 1ms it can reach 0.1ms , maybe it’s useful , and tell us about the results
Where can I buy the HFT Bot
How can i get such a bot?
