STOP INDICATOR REPAINTING

Hello. 

PLEASE READ THE FULL DESCRIPTION FIRST BEFORE YOU APPLY. 

I have been developing a candle based indicator using EAbuilder.com tool, where I just drag and drop conditions to build indicator to test some strategies. [I am not a coder of course)

However, I created a candlestick indicator which will plot an ARROW after an Engulfing candle forms and closed + if the new candles(running candle) closing price(bid/ask) price crosses above the closed candles high or low. 

But the problem is whenever price crosses the high or low of the closed engulfing/other candle, the arrow appears and signals on the chart, but after some moment if price goes below the high or low(depending on the bullish or bearish side) the arrows disappears, and again if the price goes above(for bullish closed candle) the candles high or below (for bearish closed candle) the candles low the arrows reappears in the chart. 

This arrows appearing and reappearing makes it a repainting indicator and causes false signal. (for historical back-testing or forward trading).  

I have recorded a small 40 second video (using MT4 strategy tester) of the indicator repainting to let you understand my concern. Video link is below.

It is necessary that you completely understand what I need you to do. 

I want you to write a piece of code that will make the arrow to be permanent no matter what. 

Whenever the conditions meet for the first time and an arrow appears in the chart the arrow should never be removed even if the conditions have changed due to price change and no more arrow appearing or disappearing should be happen during the running time of that candle. 

I will create more candlestick based buffers like this Engulfing pattern where the signal will occur on the running candle, so I need someone to write me a piece of code that will make a signal/arrow to be permanent on the chart.

Whenever an arrow appears, it should be  stay there. No matter how many more candlesticks buffer I put in the chart. 

Below is the snapshot of the two candlestick conditions (4 buffers) for the signals.  

I will create more indicator buffers like these using the eabuilder platform. Where the arrows will appear when after meeting all the conditions + if running candles price goes above the previous candles high (bullish arrow), or previous candles low(bearish arrow) in the chart.

So, please let me know if you can solve this for these candlestick signals I give you with the source code and also for the other candles I will create in the future in the same code page. Just remember the arrows should be permanent no matter what happens after an arrow is formed during the running candle. 

NOTE:

I have recorded a small 40 second video (using MT4 strategy tester) of the indicator repainting to let you understand my concern. Video link is below.

It is necessary that you completely understand what I need you to do. 

You can use the MT4 strategy tester to test the repainting status of any change you make. Since the indicator paints and repaints on current bar, so without live market data or strategy testers tick by tick data the indicator cant be checked visually. 

Let me know if you think you can write a piece of code to make any arrows to disappear after its first appearance in the chart. 

Please, find the source code below. 

Thanks
