During my searches, I’ve encountered several MetaTrader indicators capable of detecting Pinbars on the chart. Some of them can be found here: http://www.earnforex.com/forum/f12/random-indicators-8052/ and here: http://www.earnforex.com/forum/f12/pinbar-indicator-8377/. Unfortunately, they all have disadvantages — lack of customization parameters and even outright detection bugs. That’s why I’ve decided to create my own Pinbar …

After coding down the 3rd Generation Moving Average indicator it was a very logical step to create an expert advisor from it. Since I’ve already had the Adjustable MA EA, which offers a lot of customization of trading parameters, I’ve decided to use it as the base for the similar …

3rd Generation Moving Average was added to the list of the Forex indicators on my site today. It’s built according to the principles laid out by Dr. Manfred Dürschner and offers the least possible lag, preserving the price smoothing property of the MA. This indicator has already been coded before me, but …

I’ve finally found some time to upload a Forex expert advisor that I’ve been testing since December 2010. It’s called ATR Trailer and, as its name suggests, is based on ATR (Average True Range indicator) trailing stop. The idea behind this MetaTrader EA is …

Total Power Indicator is the latest addition to the MetaTrader indicators list on EarnForex.com. I’ve got the idea of this indicator from the June issue of the Currency Trader magazine. In short, this indicator uses Bull Power and Bear Power standard indicators to produce a more long-term perspective of the current market situation. …

If you want some help in determining the current trend direction for your trades, then my new Dots indicator is for you. It’s based on NonLagDot MetaTrader indicator. Unfortunately, the original indicator is prone to repainting its previous chart arrows based on the new data and thus isn’t a good …

When back-testing an expert advisor in MT4 Strategy Tester it is sometimes possible to encounter an error that significantly spoils the quality of testing:

TestGenerator: unmatched data error (aaa value xxx.xxx at some.date and price yyy.yyy mismatched)

where aaa is either “high” or ”low”, xxx.xxx — some price rate and yyy.yyy …

Chester Keltner developed his own version of the ”bands” indicator more than 50 years ago. Keltner Channel is an interesting and rather popular indicator, but, unfortunately, it’s not in the list of the standard MetaTrader indicators. I’ve found a basic implementation of the Keltner Channel for MT4 coded by some “Gilani” and used …

OrderSend Error 4107 is a so-called MQL4 run-time error that is similar to OrderSend Error 129 but, unlike the latter, appears only during backtesting of the MT4 expert advisors, not during their live or demo run. The error is called ERR_INVALID_PRICE_PARAM (Invalid price) in the MT4 …

Doug Schaff developed an interesting cyclical indicator for Forex trading several years ago. In 2008 he’s made it public. He presented a code of the indicator written for TradeStation EasyLanguage. Unfortunately, until now there weren’t any correctly converted versions for MetaTrader. I’ve found several variants …
