I am very familiar with Windsor Brokers and I would attempt to give you an idea about their business. Firstly, you should know that they are shifting the prices in order to Stop Out and avoid to fill your Take Profit orders. They have an internal "policy" to shift the prices for their big clients to stop out them and to maximize their profits. As AbulSameed said they do their best to collect every single penny from you if you are high exposure account for them. Secondly, be aware that they know all your orders (Stop order, Take Profit) even if you are live placing orders they shift the price in order to fill in a highier price. Finally, they are covering your position at a market marker through their automate system which first recognize your make position and then it fill your position. This make them to hold a better position that you also dealing desk delays big orders if the system didnt manage to take a better position than your order when the market is volatility is too high.
If you are still want to trade with them then good luck.

I have been dealing with Windsor for over ten years, and I have to admit that the treatment you receive there is one of a kind. But unfortunately the last two years have damaged all the great memories and relationships built over the years, the dealing room is the exact opposite of anything professional or decent. They are market makers that can manipulate prices, you will never get a fill as ordered, you always get into a long bargain of re-quotes with their dealers. They do their best to collect every single penny and even more than you already have in your account as long as they got the chance. I am very sorry to say that it is not recommended to trade with Windsor's dealing room at all.

There are better brokers out there in my opinion with more to offer. HIgher leverage, smaller lot sizes and lower spreads.

I would like to add as WB appear not to have many reviews on here, that i have been working with windsor for some time and i have not before experience such a professional broker, As a fairly experienced trader i started out with their mino account and found the platform very easy to use and later opened a standard. i feel that working with a company that is well estb and known is very important and they are authorized by all sorts of officail bodies from CySEC to FSA etc.

Excellent brokerage firm based in Cyprus, fast set up and withdrawals on accounts
