Forex simulator app ios Currencies are not.The volume-weighted frequency of order arrival as a function of depth from the top of the book should have a few forex simulator app key ios properties. The function should be 1) decreasing, 2) convex (the intuition here is app simulator ios forex difficult to explain but this is unambiguously the case empirically), 3) asymptotically approaching 0 as depth becomes infinite. Some formulationsrequire that this intensity functionto be continuously twice differentiable for tractability which is a fine and reasonable assumption but ultimately unnecessary as well. Also, there are different formulations for how to calculate “depth or distance from top of the book”. You can generally use either some “fair mid price” or the best bid and best offer for each forex simulator app ios respective side.

In either case, you, as a market maker, can adjust your quotes forex based simulator app ios on the skew of the book. Moreover, when market makers compete with each other, if the tick size is small, you often best forex ea robot 2019 see this “penny jumping” behavior. Market makers compete for fill priority by jumping each other and laddering up forex profit calculator excel on the book until some capitulation point is reached and there is a sole “winner” for fill priority.
