ОТКАЗ СИСТЕМ CHART-DERIVED
Большинств торговцы смотрят диаграмму как одно ниже, и верят они находило лицензию напечатать деньг. Оно? кажется, что производят s как раз просто 4 крест часа MACD, но он compelling результаты:

Смотрит слишком хорошо быть поистине, да, но как только завершит spreadsheet показывая профиты от этой сказовой системы, плашка брошена. The trader will trade this system through multiple failures, increasing trade sizes or widening stops until account liquidation is near, then the chart shopping ensues. But why do chart-derived systems fail?

The simple reason is that charts hide price action. Of course candlestick charts like the one above show all the highs and lows, but that?s not the whole story. The technical indicator which formed this system ? MACD in this case ? is derived from price. The price action that translated through this indicator is extremely minimal. As a result, the indicator severely lags price action, shows false signals, or shows signals at the end of price moves, just before a reversal.

Since technical indicators are quantitative in nature, why do traders rely so heavily on charts? As the clich? goes, a picture is worth a thousand words, but more than that it is a vacuum of tools in the trading markets which prevents traders from working with systems in their optimal milieu - numbers.

To work with a system in a numerical environment, a toolkit must be available which allows the trader to analyze trade data and act on it. Until recently, this type of environment was unavailable to traders, but advanced system building platforms like FX Engines have emerged to fill this void and allow the trader to construct systems quantitatively. Using actual trade feedback and statistics from live and historical testing, the trader ? with no particular math or programming aptitude ? can build expert systems that avoid the pitfalls introduced by chart-derived systems.

ESSENTIAL ELEMENTS OF SYSTEM BUILDING
System building is a 5-step process: Construction, Evaluation, Refinement, Multiplication, and Observation.

Step 1: Construction
Before any system can be constructed, the trader must make two critical choices: what currency pair(s) to trade, and whether the system is a trending system or not. Each currency pair has a different feel, and though the four majors in particular appear to be highly synched, great differences in actual trading exist. Likewise, some systems appear to be just as effective in a bear market as a bull market, while some depend heavily on being trend-synched.

- Market Entry
At the heart of every system are the signals for trade entry. These signals can take many forms, but most are essentially seeking market tops and bottoms. Once the entry triggers are determined, the entry type and schedule must be selected. Most traders are surprised to see the impact of selecting limit, stop-limit, or market as the entry type, or by allowing entry to occur only during specified time windows versus 24/6.

- Market Exit
There is an old golfing adage relevant to trading: Drive for show, putt for dough. You can make the best entry possible, but if you don?t know how to exit trades ? to book profit ? your entry prowess is meaningless.

Exits can be reactive, like fixed and trailing stops, or proactive, like limit exits and exit signals. Each exit type has pros and cons, and each will have a radically different impact on system performance. Trailing stops can be effective for capturing moderate moves, while limit exits are good for high percentage ?pip grabs?. Exit signals provide the most contextual form of exit, with technical indicators interpreting the underlying price action and inserting exit triggers into each trade.

Step 2: Evaluation
Once a system is constructed, the trader must determine its value. Each system has a bottom line value, a potential value, and a leveraged value. Historical testing is the best way to quickly determine a system?s worth. Once a test is run, the trader will be able to closely analyze the results ? even each trade ? and determine if the system is worthy of further exploration.

Step 3: Refinement
Most first attempts are flawed in some manner. Historical testing reveals these flaws, and then the trader must make refinements to the system to improve it. Are losing trades entering during a particular time more often than other times? Perhaps a more restrictive entry schedule is needed. Is the stop being hit too frequently? A stop-limit entry might help. Are winning trades yielding fewer pips, on average, than losing trades? Maybe an exit signal can solve the problem.

Step 4: Multiplication
Of course iterating through so many settings in an engine can be a laborious, tedious task. The FX Engines historical testing system includes two tools to help speed the process. The first, engine cloning, allows the trader to construct one basic engine and then clone it into several others. Each of these cloned engines can have a single parameter changed, clearing the path for the second tool: the Back Test Multiplier.

Test multiplication is a method of breaking a number of systems down into their component parts, then recombining the parts into a multiplied number of systems. Just four to six different engines can result in 50 or more multiplied systems, each with a different setup. The multiplier system then tests each of these systems. The benefits to the trader are obvious ? time is saved and non-intuitive engine improvements are made.

Step 5: Observation
Once an engine is completed the final step is to observe the engine in live test trades. Some engines may require manual manipulation, while others can trade with complete automation. Additionally, observation of an engine testing against a live price feed tells the trader how the engine will react in a variety of trading situations. Combined with historical testing, live tests validate the engine and arm the trader with the confidence required to move the engine into a real trading account…
