Amibroker formula coading help required

I would like to know MS Excel formula for below mentioned indicators:

Linsupertrend

Factor=param("Factor",3,1,3,1);

Pd=Param("ATR Periods",10,1,100,1);


Up = LinearReg((H+L)*0.5,Pd) + Factor*ATR(Pd);
Dn = LinearReg((H+L)*0.5,Pd) - Factor*ATR(Pd);

iATR=ATR(Pd);

PSA (Price Speed Acceleration)

//---- indicator buffers

extern int period = 240;
extern bool show_speed = TRUE;

int limit;

double speed[];
double acceleration[];

//+------------------------------------------------------------------+
//| Custom indicator initialization function |
//+------------------------------------------------------------------+
int init()
{
//---- indicators
IndicatorBuffers(2);

//---- drawing settings

if (show_speed == TRUE){

SetIndexStyle(0,DRAW_HISTOGRAM);

}else{

SetIndexStyle(0,DRAW_NONE);
}
SetIndexBuffer(0,speed);
SetIndexStyle(1,DRAW_LINE);
SetIndexBuffer(1,acceleration);
//----
return(0);
}
//+------------------------------------------------------------------+
//| Custom indicator deinitialization function |
//+------------------------------------------------------------------+
int deinit()
{
//----

//----
return(0);
}
//+------------------------------------------------------------------+
//| Custom indicator iteration function |
//+------------------------------------------------------------------+
int start()
{
int counted_bars=IndicatorCounted();
int i;
//----

if(counted_bars>0) counted_bars--;
limit=Bars-counted_bars;

for(i=0; i<limit; i++) {
speed = iClose(Symbol(),0,i)-iClose(Symbol(),0,i+period);
}

for(i=0; i<limit; i++) {
acceleration = speed-speed[i+period];
}

//----
return(0);

Dear traders ,
i required help on afl coading for exitprice that is if i exit my position in multiple condition then in backtest report it showing close price of that candel.but i required exact price of what my condition. for example if my condition is cross(prevdayc,l) or (h < prevdayc) or (c < ma(period,c) ; position will exit when low crossing prevdayc actual exit price is prevdayc and like this other cond also.but backtest report will show close of the candel .how to correct this .

Friends, I am currently trading NIFTY using multiple strategies with Amibroker like EMA cross, RSI cross, 20 period Hi Lo breakout and OBV . For this I am opening a new chart window and inserting each indicator which show Buy, Sell signals. In a clear trend 4 positions from 4 chart windows tiled was easy to see and trade.

Now I want to do the same for 4 more stocks and opening 4 new windows for each one is very annoying and couldnt see the chart properly with 16 open windows.

Tried to put each one in different sheet and hoping that 4 windows will be sufficient. But it didnot work. Tried to insert panes in the same window and it is very cluttering .

Friends is there any way to see and trade multiple signals for the same symbol without opening so many chart windows?

Appreciate you help in advance.
