DislikedSvm I am very interested in arbitrage PERIOD, and it doesn't have to be in FOREX. One mexican claimed if he sends 100 US$ to Guatemala, converting it to its currency and then sending the guatemalan currency to his native Mexico, it will become 1,200 pesos. If he sent $100 directly to Mexico, it will become 1,000 pesos in Mexico. I am interested in the results of your algoritm!!Ignored
The reason for time is that you have to be fast enough to find it. Otherwise, it could be gone from the market by the time you find it.
Just look at the past data of EUR/USD e.g. There are instances when the price changes more than 3 times within a second.
Tell you what. Why don't you post some prices for the majors (EUR, USD, GBP, JPY) and with spread of less than 2 pips. I'll post some results of your prices. (along with time it takes to calculate)
