Posting Indicators

Hi,

I am learning mql4. I made an indicator to get in a certain way the candle strength and create a bull-bear curve. Please let me have your comments and any suggestions for improvement. I have added a detailed description,

as comments inside the indicator file.

Thanks for testing

//|Candle Strength (CAS) Indicator with Moving Averages |
//+------------------------------------------------------------------------+
//|HELP: 1) About the Indicator 2) How to trade
//|============================================
//|1) About the Indicator:
//| All Technical Indicators are based on instrument values of a) OPEN, b) HIGH,
//|c) LOW, and d) CLOSE, while some are also using e) the VOLUME. In MetaTrader, Volume
//|is the Tick Volume, a surrogate for trade volume. The higher the volume during
//|a price move the more significant the move. To get a more concrete information
//|about Candlesticks and a measure their strength, all 5 values provided from MetaTrader
//|are used here (see calculation method below (*)). The indication provided is
//|called CAS the CAndlestick Strength. This is shown with a Histogram Gold
//|color bars. This Histogram shows also if the market is trending or ranging.
//| Depending on the instrument and time frame you can calibrate its scaling in
//|the Input Parameters. Thereafter,two Exponential Moving Averages are used, one
//|Fast and one Slow. Their difference when greater than zero should indicate entering
//|in BULL area and the inverse in BEAR area. This is seen by a dashed aqua color line.
//| In addition,with a thick Lime color line, is shown a smoothed CAS, with a
//|period to select e.g. 4 to 6,which is the Fast CAS EMA.
//|
//|2) How to trade:
//| The dashed aqua color line being the Difference of the 2 Moving Averages (moving
//|above or below zero),gives in certain circumstances a faster response for entry (buy)
//|above zero and exit (sell)below zero, while the Fast CAS EMA, called BULL_BEAR may give a
//|more conservative indication (less noise)for entry and exit.
//|Alternatively, you may enter with a small amount according the above dashed aqua
//|line and increase the entry amount after a confirmation given by the lime color
//|BULL_BEAR line. moving above zero for buy and below for sell.
//| A suggestion is to use the CAS indicator together with Alligator in main window
//|and +DMI -DMIof the ADX indicator in a separate window.
//| DISCLAIMER: Use this Indicator at your own risk.

Hi.

I am new here. Where can I post an indicator (MQL4) to discuss with others.

Thanks

Hi,

I cannot post. I received a warning:

"Unfortunately, your message cannot be added due to any of the following reasons:
1) the entry has already existed
2) there have been limits for non-approved users
3) the message interval has not reached 30 sec."

What can I do?

Thanks

AndPra: I cannot post.

Then how did you post your "I cannot post" post? Edit your post and post!
