If you have an idea of \u200b\u200bthe MetaTrader terminal, then of course you know how there are set orders to buy and sell. For those who do not know to explain briefly. When you press F9, or from the context menu when you right-click on the screen displays a window in which you select the lot size, the currency pair, expose the stop loss and take profit, in short, all the necessary parameters are asking for trade. Then the key is pressed to sell or buy, and do you expect the broker to take your application.
All these actions require neboshogo though, but all the same time. A quick trade decision-making time sharply limited, and as long as you ask the broker permission to put the order, the price can go far from the place where you originally wanted to open a position.
There is another reason why the better to automate placing orders, it is usually the same lot size traded at any given time with the deposit. That's just to automate these steps to write a script, which was originally configured lot, stop loss, take profit and when you want to open an order, you just drag the script on the chart with the pair traded. Very simple and saves time and hassle because not all DC in the apparent movement of prices tend to quickly execute your "order". They delay the execution, thereby depriving you of the apparent profit.
Species of the script a few. The archive contains 4 script, of which 2 Buy and Sell open position at the current price, and 2 - Buy_Stop_Limit Sell_Stop_Limit and set pending orders. By default, the scripts are set to lot size is 0.01 and the levels of stop loss, take profit equal to 0pt. To change these values \u200b\u200byou must open the desired script in a text editor and change the required parameters.
