Reduce your costs with VPS
For example, your computer with a monitor that uses 200 watts per hour at a location where the electric rate is $0.12 per kW hour flat rate, as there are 8 760 hours in a year, the total electrical cost would be ((200*8760)/1000)*0.12= $210.24 a year.
Let’s say your computer costs $1,000 and after a year of continuous operation, it is depreciated by 20%, which means that you have lost another $200. As result, your total expenses $210.24 + $200 (electricity + depreciation) = $410.24
For example, your trading terminal on your home PC sends a buy GBPUSD order at 1.29700. However, it reaches to the server 400 milliseconds later when the price is already 1.29710. As a result, your potential profit will be 10 points less.
Let’s assume you are trading with 100K lots. Thus due to slippage, caused by latency of 400 milliseconds, you’re losing $10 / per lot
My first VPS was with the most popular company and I found it incredibly laggy, and it would just freeze up, I kept upgrading there and it didn't get better. For less money I got this service in the same location (London) and it works really well. I'm not techy but I think their processors are faster or something. This is how VPS is supposed to work.
