On nse site there is category called SLBM. You can check prices there historic as well. Period is generally month or 2 price is higher for 2 months than 1 month it folows F&O expiry date for lending
Shares are credited back in your account.

Generally from what i have observed is yield is around 0.5 -1% max. Opportunity is infrequent.

I have done slbm 2 years back where hdfc bank had everymonth opportunity. For once in a while i dont know if it makes sense personally doesnt even make 0.1 -0.3 % of portfolio yield in a year .

Broker can help facilitate the same dont know for online platforms.

Sealmatic has shared its annual report. There is nothing new in the report, in the sense that the company has been very prompt in reporting developments to Stock exchanges. One para I like-
“The business area of Defence and Nuclear is now well covered by achieving the certification of ISO 19443 (Nuclear) and the DGQA (Defence), it would be noteworthy to mention that Sealmatic was the second company in India to get the ISO 19443 certification and also to get the coveted DGQA certification for Defence through a very stringent process, having achieved both these certificates it has paved way for us to penetrate the coveted markets, which are long term, profitable and sustainable. We have established a team of engineers who will exclusively pursue this business in the Defence and Nuclear sector.”
There have also explained middle east and Russian opportunity. A good read.
