Hello,
I modified a similar Indicator in my Coding library and this version meet all requirements, and I'm ready to send you a Demo version.
Here are some functions of Indicator:
1./ Can set all parameters related to Bollinger Bands and Stochastic Indicator as in standard Indicator in MT4
2./ Can select use or not the Stochastic (UseSTO = true/false), also can change Stochastic Overbought/Oversold level (current version use the Main Line of Stochastic)
3./ Have all 4 types of alert: Popup, Sound, Email, Push alert. Can select Instantly alert when condition met, or only alert when candle closed (InstantAlert = true/false). Can turn off/on each alert type. Alert message is very informative, include Buy/Sell, Time frame, Time, and Pair.
4./ Indicator show Buy/Sell arrows as signal. You can also attach Bollinger Bands and STO to chart (of course, BBands and Stochastic have the same value as set in Indicator to avoid confusion) for visual check the signal.
Please message me so that I can send you a Demo version to check. I hope we have a good deal.
