CE and PE
CE is a call option, PE is a put option. A CE call expects the index or stock to go up; a PE call expects it to go down. “NIFTY 24500 CE” is the NIFTY call option at the 24500 strike. Some channels write “calls” and “puts”, or just “C” and “P”; they mean the same thing.
The strike
The number before CE or PE, such as 24500, is the strike: the level the option is built on. The price you pay is the premium, a much smaller number. The entry, stop-loss and target in a call are usually premiums. A channel that gives its stop-loss as a level of the index instead is read as having given none, and your channel's default stop applies.
“above 82/85”
A breakout level, not a price to pay. The trade starts only when the premium rises to that level; until then there is nothing to buy. When a channel gives a pair, “above 82/85”, the trade starts at the higher one. “abv”, “cross” and “wait for level” mean the same. Trade Arena places it as a stop order at that level. If the premium has already run well past the level by the time the call is read, the move is gone, and the call is not chased.
“@ 118-120” and “buy at cmp”
A price to pay now. CMP is the current market price, so “buy at cmp” means buy at whatever the premium is as you read it, and “@ 118-120” names the range the channel expects you to get. Trade Arena never sends a market order: it places a limit order just above the live price, so a fast move cannot fill you far from the call.
SL, TGT, TP, T1 and T2
SL is the stop-loss, the premium at which the trade is closed for a loss. TGT, TP, T1 and T2 are the targets; “TGT 95/110” gives a first and a second target. If a call gives no stop-loss or no target, Trade Arena never guesses one: your channel's default stop and target apply, taken from the real entry price.
“++”, “running 100+” and the rocket emoji
Run updates. The channel is reporting where the premium has gone since the call: “92++”, “running 100+”, a row of rockets. They are not new calls, and Trade Arena never reads one as a second entry on a contract it already holds. A run update becomes an instruction only when it says what to do: “book”, “exit”, “trail”, a new SL.
“book partial”, “exit half”, “book 50%”
Close part of the position and let the rest run. “Book profit” and “book some” are read the same way. Trade Arena books the part named and keeps the stop-loss on what is left.
“trail SL to cost”
Move the stop-loss up to the entry price, so the trade can no longer lose. “Trail SL to 90” moves it to 90. Trade Arena applies it, with one rule: a later message can tighten the stop or exit early, but it can never widen the stop you started with.
A call in two messages
Many channels post the contract first — “BANKNIFTY 57700 PE” — and the entry, stop-loss and target a minute later. Trade Arena reads the channel as a conversation, not one message at a time: the first half is held for ten minutes and completed by the next message, so the two become one call.
Weekly and monthly expiry
“This week”, “next week” and “monthly” say which contract a call means. Some index contracts expire every week, others once a month, and the exchange changes the days from time to time. Trade Arena takes the expiry from the exchange's own contract list, synced every morning, so the call names the contract that actually trades that week.
Lots and quantity
Options trade in lots. One lot is a fixed number of units set by the exchange, different for every index and stock, and changed from time to time. “2 lots” means two of them. Lot sizes are read from the exchange master every morning, so a call for two lots becomes the right quantity on the day.
