I tried to make a custom indicator of the price at the bands with these settings.UPPER BAND: AVGC50 + 2.5 * SQR(ABS(C ^ 2.5 + C1 ^ 2.5 + C2 ^ 2.5 + C3 ^ 2.5 + C4 ^ 2.5 + C5 ^ 2.5 + C6 ^ 2.5 + C7 ^ 2.5 + C8 ^ 2.5 + C9 ^ 2.5 + C10 ^ 2.5 + C11 ^ 2.5 + C12 ^ 2.5 + C13 ^ 2.5 + C14 ^ 2.5 + C15 ^ 2.5 + C16 ^ 2.5 + C17 ^ 2.5 + C18 ^ 2.5 + C19 ^ 2.5 + C20 ^ 2.5 + C21 ^ 2.5 + C22 ^ 2.5 + C23 ^ 2.5 + C24 ^ 2.5 + C25 ^ 2.5 + C26 ^ 2.5 + C27 ^ 2.5 + C28 ^ 2.5 + C29 ^ 2.5 + C30 ^ 2.5 + C31 ^ 2.5 + C32 ^ 2.5 + C33 ^ 2.5 + C34 ^ 2.5 + C35 ^ 2.5 + C36 ^ 2.5 + C37 ^ 2.5 + C38 ^ 2.5 + C39 ^ 2.5 + C40 ^ 2.5 + C41 ^ 2.5 + C42 ^ 2.5 + C43 ^ 2.5 + C44 ^ 2.5 + C45 ^ 2.5 + C46 ^ 2.5 + C47 ^ 2.5 + C48 ^ 2.5 + C49 ^ 2.5 - 50 * AVGC50 ^ 2.5) / 49) LOWER BAND: AVGC50 - 2.5 * SQR(ABS(C ^ 2.5 + C1 ^ 2.5 + C2 ^ 2.5 + C3 ^ 2.5 + C4 ^ 2.5 + C5 ^ 2.5 + C6 ^ 2.5 + C7 ^ 2.5 + C8 ^ 2.5 + C9 ^ 2.5 + C10 ^ 2.5 + C11 ^ 2.5 + C12 ^ 2.5 + C13 ^ 2.5 + C14 ^ 2.5 + C15 ^ 2.5 + C16 ^ 2.5 + C17 ^ 2.5 + C18 ^ 2.5 + C19 ^ 2.5 + C20 ^ 2.5 + C21 ^ 2.5 + C22 ^ 2.5 + C23 ^ 2.5 + C24 ^ 2.5 + C25 ^ 2.5 + C26 ^ 2.5 + C27 ^ 2.5 + C28 ^ 2.5 + C29 ^ 2.5 + C30 ^ 2.5 + C31 ^ 2.5 + C32 ^ 2.5 + C33 ^ 2.5 + C34 ^ 2.5 + C35 ^ 2.5 + C36 ^ 2.5 + C37 ^ 2.5 + C38 ^ 2.5 + C39 ^ 2.5 + C40 ^ 2.5 + C41 ^ 2.5 + C42 ^ 2.5 + C43 ^ 2.5 + C44 ^ 2.5 + C45 ^ 2.5 + C46 ^ 2.5 + C47 ^ 2.5 + C48 ^ 2.5 + C49 ^ 2.5 - 50 * AVGC50 ^ 2.5) / 49) ARE THESE CORRECT

Please try the following instead:

Upper BB 50,25:

AVGC50 + 2.5 * SQR(ABS(C ^ 2 + C1 ^ 2 + C2 ^ 2 + C3 ^ 2 + C4 ^ 2 + C5 ^ 2 + C6 ^ 2 + C7 ^ 2 + C8 ^ 2 + C9 ^ 2 + C10 ^ 2 + C11 ^ 2 + C12 ^ 2 + C13 ^ 2 + C14 ^ 2 + C15 ^ 2 + C16 ^ 2 + C17 ^ 2 + C18 ^ 2 + C19 ^ 2 + C20 ^ 2 + C21 ^ 2 + C22 ^ 2 + C23 ^ 2 + C24 ^ 2 + C25 ^ 2 + C26 ^ 2 + C27 ^ 2 + C28 ^ 2 + C29 ^ 2 + C30 ^ 2 + C31 ^ 2 + C32 ^ 2 + C33 ^ 2 + C34 ^ 2 + C35 ^ 2 + C36 ^ 2 + C37 ^ 2 + C38 ^ 2 + C39 ^ 2 + C40 ^ 2 + C41 ^ 2 + C42 ^ 2 + C43 ^ 2 + C44 ^ 2 + C45 ^ 2 + C46 ^ 2 + C47 ^ 2 + C48 ^ 2 + C49 ^ 2 - 50 * AVGC50 ^ 2) / 49)

Lower BB 50,25:

AVGC50 - 2.5 * SQR(ABS(C ^ 2 + C1 ^ 2 + C2 ^ 2 + C3 ^ 2 + C4 ^ 2 + C5 ^ 2 + C6 ^ 2 + C7 ^ 2 + C8 ^ 2 + C9 ^ 2 + C10 ^ 2 + C11 ^ 2 + C12 ^ 2 + C13 ^ 2 + C14 ^ 2 + C15 ^ 2 + C16 ^ 2 + C17 ^ 2 + C18 ^ 2 + C19 ^ 2 + C20 ^ 2 + C21 ^ 2 + C22 ^ 2 + C23 ^ 2 + C24 ^ 2 + C25 ^ 2 + C26 ^ 2 + C27 ^ 2 + C28 ^ 2 + C29 ^ 2 + C30 ^ 2 + C31 ^ 2 + C32 ^ 2 + C33 ^ 2 + C34 ^ 2 + C35 ^ 2 + C36 ^ 2 + C37 ^ 2 + C38 ^ 2 + C39 ^ 2 + C40 ^ 2 + C41 ^ 2 + C42 ^ 2 + C43 ^ 2 + C44 ^ 2 + C45 ^ 2 + C46 ^ 2 + C47 ^ 2 + C48 ^ 2 + C49 ^ 2 - 50 * AVGC50 ^ 2) / 49)

That said, it is generally easier to just add the Bollinger Band Indicator to the Chart if you want to Plot it in TeleChart. You may wish to review the following:
