A,

Trades occur.

IF. Price line comes in contact in realtime with Lower. band and at the end of the candle the price and ma1 lie within BANDS  

     THEN BUY,HOLDBUY or CLOSE SELL & BUY 

IF. Price line comes in contact in realtime with Upper. BAND1 and at the end of the candle the price and ma1 lie within BAND1 bands

     THEN SELL,HOLDSELL or CLOSE BUY & SELL

if ma1 becomes > upper band

or ma1 becomes < lower band

Then  close trade

When ma1 moves out of range of a particular band that band becomes inactive while the other band becomes active. 

 I would like for there to be 20 bands.

e.g

BAND1

UPPER BAND=1000;

LOWER BAND= 500;

BAND2 

 UPPER BAND=400;

LOWER BAND=100;

 .

BAND20

UPPER BAND =1

LOWER BAND =0

ETC.
