Programmer assistance requested for Schaff EA

I need some help with this EA. Here are the problems:

1) The entry/exit is one bar late. On the attached chart, the 1st vertical aqua line is where entry should have been at cross above 25. The arrow from strategy tester on the next bar is where entry actually occurred.

b) the 2nd vertical aqua line is where exit should have been cross below 80. The arrow from strategy tester on the next bar is where exit actually occurred.

2) There is no sell entry at cross below 85, and thus no sell exit, which should have been at cross above 20. Many sell entries are not generated using strategy tester.

Here are the signals for the EA:

Open BUY (LONG) when cross UP 25% level and Close BUY when cross DOWN 80% level.
Open SELL (SHORT) when cross DOWN 85% level dan Close SELL when cross UP 20% level.

Description of attachments:
1) Schaff EA
2) Schaff indicator
3) Template with the indicator/levels

I would appreciate it if anyone can find out why the signals are one bar late and why most of the sell entries are not generated.

how can you NOT know this???

I'm not a programmer, but I do know that the signals generated do not correspond to the levels where the entries/exits are supposed to occur. I asked for help, and if you can't help, why bother responding?

It works correctly... the signals are not generated until the bar formation is complete therefore signals based on indicators are always 1 bar late.

Thanks, but why then aren't all the sell signals being generated?

The source codes are too badly written, with virtually no use of indentations whatsoever and very limited use of functions. I'm afraid my level of patience doesn't allow me to even try and understand this piece of code.

I think it's easier to do a new one from the ground up.
