Forex Koder Killer Expert Advisor

Forex Koder Killer Expert Advisor review:

With this EA you can say goodbye to your coder and save bucks from your pocket!

Did you find out an interesting holy grail indicator and you want to test it on your own? Eager to know if it will be profitable on long term?

Well, here it is the Koder Killer EA.

Simple steps to follow

  • open your indicator source code
  • search for the Set Index Buffer values
  • copy the values into the EA
  • set all the other features
  • backtest your strategy FOR FREE
  • run your EA on live servers paying a small rent fee.

Some integrated features

  • auto money management
  • check of slippage and spread
  • close at opposite signal
  • martingale
  • time filter
  • RSI filter
  • MA filter
  • MA cross
  • Stochastic cross

All of these features will help to find the best setup for your indicator… It is a value added, something that any coder will ask to pay for any single function added to your EA!

Some technical details

A well-coded indicator must return zero or empty value 2147483647 (0x7FFFFFFF) on normal running.

At this point, once the conditions are matching and the arrow appears, the buffer will return a different value (usually the price value). At the same time, the EA will recognize a mismatch between zero or empty value and buffer value and will open an order accordingly.

You can double check this procedure by running a visual backtesting: on the top-left corner of the chart, you will see the returned value of the indicator (check the screenshots attached).

Last but not least, in order to enable your custom indicator, make sure you use the following MagicNumber: 20151119, otherwise the custom indicator will be disabled.

Final consideration

Some custom indicators are very complex and will not run with this EA, but will be very useful when you have simple indicators with BUY and SELL buffers. At least you can try for free, and if it does not work, you just spent your time and not your money!
