La grille peut être personnalisée Les acheteurs et les vendeurs: La grille suspendra les factures à partir du prix initial, à chaque paiement. L'intervalle de prix de la grille. Ce paramètre, le nombre de factures suspendues est "nombre de billets", suffisant. Les acheteurs sont les suivants: C'est exactement le contraire.
Le plus grand risque stratégique est le marché unilatérale, où les prix fluctuent au-delà de la grille.
La grille est équipée d'un arrêt automatique et d'une fonction mobile.
// Grid can customize direction
// Basic trading operation: buy first and then sell.
// The grid will start to send buying order at the price that below the first price, which is the price follow
// by the first price (second latest buying price, third latest buying price…and so on). Each buying order is separated by
// the "price interval" parameter. The number of pending orders is "single quantity", and will send the order total until
// the "total quantity" is filled.
// After any buying order is completed, the program will be on the basis of the buying price, add the price of the "price
// difference" parameter to the sell price, after the order has been sold, and then re-start the progress of this
// grid strategy (checking, place order, wait until it executed, sell)
// Selling short first and then buy to cover: the operation is just the opposite
// The biggest risk of this strategy is when the market trend is unilateral moving, and the price fluctuations are exceeding the grid.
// The following code has made the grid with automatic stop loss and movement function.
// Comments:
// The strategy uses a virtual pending order design, which provides a great deal of processing for the exchange to limit the number
// of pending orders, and solves the problem flexibly.
// The grid logic is flexible in design and clever in structure.
// Profit and loss calculation, each numerical statistical algorithm can be used for reference, and each condition detection design
// is rigorous. (for minimize the possibility of BUG)
// The source code is very worth learning.
