    Modification of characteristics for the previously opened position or pending orders. If the function succeeds, the returned value will be TRUE. If the function fails, the returned value will be FALSE. To get the detailed error information, call GetLastError() function.

public boolean orderSelect(int index,
                  SelectionType select,
                  SelectionPool pool)
```
    The function selects an order for further processing. It returns TRUE if the function succeeds. It returns FALSE if the function fails. To get the error information, one has to call the GetLastError() function. The pool parameter is ignored if the order is selected by the ticket number. The ticket number is a unique order identifier. To find out from what list the order has been selected, its close time must be analyzed. If the order close time equals to 0, the order is open or pending and taken from the terminal open positions list. One can distinguish an open position from a pending order by the order type. If the order close time does not equal to 0, the order is a closed order or a deleted pending order and was selected from the terminal history. They also differ from each other by their order types.
    
    Parameters:
    index - Order index or order ticket depending on the second parameter.
    select - Selecting flags. It can be any of the following values: SELECT_BY_POS - index in the order pool, SELECT_BY_TICKET - index is order ticket.
    pool - Optional order pool index. Used when the selected parameter is SELECT_BY_POS. It can be any of the following values: MODE_TRADES (default)- order selected from trading pool(opened and pending orders), MODE_HISTORY - order selected from history pool (closed and canceled order).
    
    Returns:
    The function selects an order for further processing. It returns TRUE if the function succeeds. It returns FALSE if the function fails. To get the error information, one has to call the GetLastError() function. The pool parameter is ignored if the order is selected by the ticket number. The ticket number is a unique order identifier.

```
    The main function used to open a position or place a pending order. Returns number of the ticket assigned to the order by the trade server or -1 if it fails. To get additional error information, one has to call the GetLastError() function. Notes: At opening of a market order (OP_SELL or OP_BUY), only the latest prices of Bid (for selling) or Ask (for buying) can be used as open price. If operation is performed with a security differing from the current one, the MarketInfo() function must be used with MODE_BID or MODE_ASK parameter for the latest quotes for this security to be obtained. Calculated or unnormalized price cannot be applied. If there has not been the requested open price in the price thread or it has not been normalized according to the amount of digits after decimal point, the error 129 (ERR_INVALID_PRICE) will be generated. If the requested open price is fully out of date, the error 138 (ERR_REQUOTE) will be generated independently on the slippage parameter. If the requested price is out of date, but present in the thread, the position will be opened at the current price and only if the current price lies within the range of price+-slippage. StopLoss and TakeProfit levels cannot be too close to the market. The minimal distance of stop levels in points can be obtained using the MarketInfo() function with MODE_STOPLEVEL parameter. In the case of erroneous or unnormalized stop levels, the error 130 (ERR_INVALID_STOPS) will be generated. At placing of a pending order, the open price cannot be too close to the market. The minimal distance of the pending price from the current market one in points can be obtained using the MarketInfo() function with the MODE_STOPLEVEL parameter. In case of false open price of a pending order, the error 130 (ERR_INVALID_STOPS) will be generated. Applying of pending order expiration time can be disabled in some trade servers. In this case, when a non-zero value is specified in the expiration parameter, the error 147 (ERR_TRADE_EXPIRATION_DENIED) will be generated. On some trade servers, the total amount of open and pending orders can be limited. If this limit has been exceeded, no new position will be opened (or no pending order will be placed) and trade server will return error 148 (ERR_TRADE_TOO_MANY_ORDERS).
    
    Parameters:
    symbol - Symbol for trading.
    cmd - Operation type. It can be any of the Trade operation enumeration.
    volume - Number of lots.
    price - Preferred price of the trade.
    slippage - Maximum price slippage for buy or sell orders in points.
    stoploss - StopLoss level.
    takeprofit - TakeProfit level.
    comment - Order comment text. Last part of the comment may be changed by server.
    magic - Order magic number. May be used as user defined identifier.
    expiration - Order expiration time (for pending orders only).
    arrowColor - Color of the arrow on the chart. If the parameter is missing or has CLR_NONE value closing arrow will not be drawn on the chart.
    
    Returns:
    The main function used to open a position or place a pending order. Returns number of the ticket assigned to the order by the trade server or -1 if it fails. To get additional error information, one has to call the GetLastError() function. Notes: At opening of a market order (OP_SELL or OP_BUY), only the latest prices of Bid (for selling) or Ask (for buying) can be used as open price. If operation is performed with a security differing from the current one, the MarketInfo() function must be used with MODE_BID or MODE_ASK parameter for the latest quotes for this security to be obtained. Calculated or unnormalized price cannot be applied. If there has not been the requested open price in the price thread or it has not been normalized according to the amount of digits after decimal point, the error 129 (ERR_INVALID_PRICE) will be generated. If the requested open price is fully out of date, the error 138 (ERR_REQUOTE) will be generated independently on the slippage parameter. If the requested price is out of date, but present in the thread, the position will be opened at the current price and only if the current price lies within the range of price+-slippage. StopLoss and TakeProfit levels cannot be too close to the market. The minimal distance of stop levels in points can be obtained using the MarketInfo() function with MODE_STOPLEVEL parameter. In the case of erroneous or unnormalized stop levels, the error 130 (ERR_INVALID_STOPS) will be generated. At placing of a pending order, the open price cannot be too close to the market. The minimal distance of the pending price from the current market one in points can be obtained using the MarketInfo() function with the MODE_STOPLEVEL parameter. In case of false open price of a pending order, the error 130 (ERR_INVALID_STOPS) will be generated. Applying of pending order expiration time can be disabled in some trade servers.
