EA needed to automatically buy & sell on specific candle closes

I am looking for an EA to be built that buys after 2 bullish candle closes following a bearish candle, and sells after 2 bearish candle closes following a bullish candle. This process repeats whilst the EA is active and so the EA is constantly buying and selling when each setup occurs - closing the previous open order to open a new (opposing) position.

This will be used on DAX CFD and will just need an adjustable lot size variable, as no stop loss or take profit is needed since the EA will automatically close a no longer valid position.

This will be attached to an offline renko chart (created using another EA), however this shouldn't affect anything as this chart is able to have EAs attached and working to it.

I would also like the option to select whether the EA takes buys and sells, just buys, or just sells.

The key to this EA will be its ability to recognise and execute setups as quickly as possible.

I have attached a video (manual testing on mt4) for what I want the EA to do (but mt5).

Thanks
