//=============================================================================
// OrderSendReliable()
//
// This is intended to be a drop-in replacement for OrderSend() which,
// one hopes, is more resistant to various forms of errors prevalent
// with MetaTrader.
//
// RETURN VALUE:
//
// Ticket number or -1 under some error conditions. Check
// final error returned by Metatrader with OrderReliableLastErr().
// This will reset the value from GetLastError(), so in that sense it cannot
// be a total drop-in replacement due to Metatrader flaw.
//
// FEATURES:
//
// * Re-trying under some error conditions, sleeping a random
// time defined by an exponential probability distribution.
//
// * Automatic normalization of Digits
//
// * Automatically makes sure that stop levels are more than
// the minimum stop distance, as given by the server. If they
// are too close, they are adjusted.
//
// * Automatically converts stop orders to market orders
// when the stop orders are rejected by the server for
// being to close to market. NOTE: This intentionally
// applies only to OP_BUYSTOP and OP_SELLSTOP,
// OP_BUYLIMIT and OP_SELLLIMIT are not converted to market
// orders and so for prices which are too close to current
// this function is likely to loop a few times and return
// with the “invalid stops” error message.
// Note, the commentary in previous versions erroneously said
// that limit orders would be converted. Note also
// that entering a BUYSTOP or SELLSTOP new order is distinct
// from setting a stoploss on an outstanding order; use
// OrderModifyReliable() for that.
//
// * Displays various error messages on the log for debugging.

// OrderSendReliableMKT()
//
// This is intended to be an alternative for OrderSendReliable() which
// will update market-orders in the retry loop with the current Bid or Ask.
// Hence with market orders there is a greater likelihood that the trade will
// be executed versus OrderSendReliable(), and a greater likelihood it will
// be executed at a price worse than the entry price due to price movement.
//
// RETURN VALUE:
//
// Ticket number or -1 under some error conditions. Check
// final error returned by Metatrader with OrderReliableLastErr().
// This will reset the value from GetLastError(), so in that sense it cannot
// be a total drop-in replacement due to Metatrader flaw.
//
// FEATURES:
//
// * Most features of OrderSendReliable() but for market orders only.
// Command must be OP_BUY or OP_SELL, and specify Bid or Ask at
// the time of the call.
//
// * If price moves in an unfavorable direction during the loop,
// e.g. from requotes, then the slippage variable it uses in
// the real attempt to the server will be decremented from the passed
// value by that amount, down to a minimum of zero. If the current
// price is too far from the entry value minus slippage then it
// will not attempt an order, and it will signal, manually,
// an ERR_INVALID_PRICE (displayed to log as usual) and will continue
// to loop the usual number of times.
//
// * Displays various error messages on the log for debugging.
