EA based on HalfTrend indicator

The EA should be flexible and trade various underlyings and run on multiple brokers at the same time as well as on different time frames on real money accounts after successful back and front testing.

EA open trades in both direction. All trades (first buy or first sell) are opened at the begining of a new bar to prevent false signals.
If there is an opened position, and there is a opposite signal, the opened position doesn't have be closed. Just a new one must be opened in the opposite direction.

EA will need to contain the following:

• Halftrend indicator builtin for signal
• Halftrend indicator builtin for filtering signal
• Standard money managements, lot size, SL, TP, Trailing Stop, account margin check are required
• Hedge and Martingale
• Max orders
• Slippage Limit
• Trading times restriction
• Spread restriction
• Option to just trade only with Halftrend signals without specific conditions to be agreed (means others indi disabled)
• Display BUY/SELL breakeven/profit lines
• all informations about: Buy/Sell lots, Buy/Sell profit, free margin, equity
• Different buttons in the chart : close buy, close sell, close all, trade sell, trade buy, new cycle

The basic entry and exit rules will be provided in details to the selected developer as well as the indicators to use as. This is an overview of the rules

Long Entry Rules:

1. If the DeepSkyBlue upward pointing arrow of the HalfTrend indicator along with its lower indicator line gets aligned fairly below price bars
2. If another indicator used as filter it must confirm the halftrend signal. Suppose we use the stochastic => Stochastic confirms the direction proposed by halftrend and stochastic is not in the overbought/oversold range (which would be a setting variable in the EA).

Sell Entry Rules:

1. If the Tomato upward pointing arrow of the HalfTrend indicator along with its lower indicator line gets aligned fairly above price bars
2. If another indicator used as filter it must confirm the halftrend signal

The expert advisor should come with the source code(.mq4)

My first specification is to get a great developer not a beginner. Great to make a great code and great to code quickly without bugs.

Thanks for reading me - If you are a beginner, please do not make me waste my time.

I will review all applications by the end of the day and select up to 3 potential coders, thank you to all coders applying.
Interested coder should be willing to have a voice communication(via zoom, WhatsApp, etc.) for enhance and seamless understanding if the need arises.

Great developers, welcome ! !

Best regards
