Las redes pueden ser personalizadas. Primero compra y luego venta: La parámetro, el número de facturas que se cuelgan es "número de monedas", suficiente para colgar el número total de facturas que se cuelgan una factura, después de la transacción de una factura arbitraria, el programa añadirá el precio de compra en función de la diferencia de precio de la factura. El precio del valor de este parámetro cuelga la oferta, vende, vende y luego vuelve a colgar la compra según el precio original de la red. Los primeros en vender y después comprar: La operación es exactamente al revés.
El mayor riesgo estratégico es el mercado unilateral, donde los precios fluctúan más allá de los límites de la red.
Grilla con función de auto-destrucción y movilidad
// 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.
