One might sensibly ask why I'm posting it if it has all these limitations? The rationale here is that I want individuals of all levels to realise that building algorithmic trading systems is hard work and requires a lot of attention to detail! There is a significant amount of scope for introducing bugs and incorrect behaviour. I want to outline how "real world" systems are built and show you how to test for these errors and correct them.
Let's presume that the market keeps on going against you. In this case, the broker will simply have no choice but to shut down all your losing positions. This limit is referred to as a stop out level. For example, when the stop out level is established at 5% by a broker, the trading platform will start closing your losing positions automatically if your margin level reaches 5%. It is important to note that it starts closing from the biggest losing position.
It is essential that traders understand the margin close out rule specified by the broker in order to avoid the liquidation of current positions. When an account is placed on margin call, the account will need to be funded immediately to avoid the liquidation of current open positions. Brokers do this in order to bring the account equity back up to an acceptable level.
This is a very large question, as many important factors other than Forex robots influence your trading profits, the first and most important of them is yourself and how self confident you are, your available investment capital, the broker you are trading with, the currency pairs you prefer to trade, the market conditions while trading and finally the Forex robot you would choose! While a good Forex Robot can limit those factors bad effects on your profits or even abolish them, no one can predict exactly how much you can gain!
